Conventional and High-Strength Headed Bars—Part 2: Data Analysis

ACI STRUCTURAL JOURNAL TECHNICAL PAPER Title No. 116-S71 Conventional and High-Strength Headed Bars—Part 2: Data Analysis by Krishna P. Ghimire, Yun Shao, David Darwin, and Matthew O’Reilly Equations to characterize the anchorage strength of headed bars were developed, incorporating key factors affecting anchorage strength: concrete compressive strength; embedment length; bar diameter; spacing between the bars; and confining reinforcement parallel to the headed bars. Results from tests of 138 exterior beam-column joints, 64 without and 74 with confining reinforcement within the joint region, were used to develop the equations. Concrete compressive strengths ranged from 4050 to 16,030 psi (27.9 to 110.6 MPa) and bar stresses at failure ranged from 33,100 to 153,160 psi (228 to 1056 MPa). The bearing area of the headed bars ranged from 3.8 to 9.5 times the area of the bar. Some headed bars contained obstructions adjacent to the head that exceeded the dimensions permitted for HA heads in ACI 318-14 and ASTM A970-13a but are now permitted by ASTM A970-18. The test results show that headed bar anchorage strength is proportional to the concrete compressive strength raised to the power 0.24. The contribution of confining reinforcement is proportional to the area of confining reinforcement parallel to the headed bar within eight to 10 bar diameters of the headed bar. Headed bars with obstructions larger than those permitted in ACI 318-14 that meet the provisions in ASTM A970-18 exhibit anchorage strengths that are similar to those that meet the provisions in ACI 318-14. Keywords: anchorage; beam-column joints; bond and development; headed bars; high-strength concrete, high-strength steel; reinforcement. INTRODUCTION Headed bars are often used to anchor reinforcing steel as a means of reducing congestion where member geometry precludes adequate anchorage with a straight bar. Prior to the current study (Shao et al. 2016; Ghimire et al. 2018, 2019), only limited results were available on the behavior of headed bars, with no data on high-strength headed bars or applications dealing with high-strength concrete. The design provisions in ACI 318, which first appeared in ACI 318-08, are based on the analysis of a small number of test specimens with a limited range of concrete compressive strengths and bar stresses at failure (DeVries et al. 1998, 1999; Thompson et al. 2005, 2006a,b). None of the tests involved beamcolumn joints. Due to the lack of experimental information, the design provisions for development length of headed reinforcing bars in ACI 318-14 limit the yield strength of headed reinforcing steel to 60,000 psi (420 MPa) and the concrete compressive strength for calculating development length to 6000 psi (40 MPa). ACI 318-14 also requires the clear spacing between the bars to be at least four times the bar diameter and does not account for the contribution of confining reinforcement to anchorage strength. These limits restrict the use of headed bars and prevent the full benefits of higher-strength reinforcing steel and concrete from being ACI Structural Journal/May 2019 realized. The purpose of this study is to identify the primary factors that affect the anchorage strength of the headed bars and develop an expression that characterizes the anchorage strength of the headed bars that incorporates the key parameters and is applicable to the full range of concrete and steel strengths used in construction. The study includes an evaluation of headed bars with obstructions that exceed the dimensions permitted by ACI 318-14. The equation for the development length of headed bars in tension, ℓdt (in. or mm) in Section 25.4.4.2 of ACI 318-14, is  0.016 f y ψ e   dt =   db (in.-lb) f c′   (1a)  0.19 f y ψ e   dt =   db (SI) f c′   (1b) where fy is the yield strength of the bar (psi or MPa), with an upper limit of 60,000 psi (420 MPa); fc′ is the compressive strength of concrete (psi or MPa), with an upper limit of 6000 psi (40 MPa); db is the bar diameter (in. or mm); and ψe the is modification factor for epoxy-coated or zinc and epoxy dual-coated bars. The development length ℓdt may be no less than the larger of 8db or 6 in. (150 mm). To enable comparison of Eq. (1) with test results, the equation is solved for the stress in the headed bar, replacing ℓdt with ℓeh, corresponding to the actual embedment length (measured from the critical section to the bearing face of the head). fy is replaced by fs,ACI, and fc′ is replaced by fcm, giving f s , ACI =  eh f cm 0.016db ψ e f s , ACI =  eh f cm 0.19db ψ e (in.-lb) (2a) (SI) (2b) For a given embedment length, Eq. (2) indicates that the stress developed in a headed bar corresponding to an anchorage failure is proportional to the square root of ACI Structural Journal, V. 116, No. 3, May 2019.

As demonstrated by Shao et al. (2016) and Ghimire et al. (2019), however, the square root of concrete compressive strength overestimates the increase in stress in the bar as the compressive strength increases, and the stress drops more rapidly with increased bar size than characterized by the inverse of the bar diameter. Specifically, Eq. (2) is very conservative in predicting the anchorage strength of headed No. 5 (No. 16) bars but becomes progressively less conservative with increasing bar size and concrete compressive strength. These observations demonstrate that the current provisions (ACI 318-14) for the development length of headed bars are not applicable over the full range of concrete compressive strengths and bar sizes used in practice. To address these inconsistencies and incorporate key factors affecting the anchorage strength of headed bars including concrete compressive strength, embedment length, bar diameter, spacing between the bars, and confining reinforcement, descriptive equations are developed that accurately characterize the anchorage strength of the headed bars. RESEARCH SIGNIFICANCE Expressions that characterize the anchorage strength of headed bars in concrete are scarce in the literature. Those that are available are either too specific to the tests from which they were developed or do not address the full range of factors affecting anchorage strength. This paper aims to develop descriptive equations for the anchorage strength of headed bars that are applicable over the full range of concrete and steel strengths currently used in construction, along with the other key factors that control anchorage strength. HEADED BAR DATABASE As part of a comprehensive study on the anchorage behavior of headed bars (Shao et al. 2016; Ghimire et al. 2018, 2019), 202 exterior beam-column joint specimens were tested under monotonic loading. The key parameters studied were concrete compressive strength, bar size, embedment length, head size, spacing between the bars, and confining reinforcement within the joint region. Results from 138 out of the 202 specimens, 64 without and 74 with confining reinforcement within the joint region, were used to develop descriptive equations for the anchorage strength of the headed bars. Specimens that provided a wide range of the key parameters affecting the anchorage strength of headed bars were selected. Headed bars without and with confining reinforcement within the joint region were considered. Specimens with bars containing heads with net bearing areas of 3.8 to 9.5Ab (Ab is nominal bar area) and side cover of 2.5 to 4 in. (65 to 100 mm) were selected as the data set used to develop the descriptive equations. Specimens with large heads (12.9 to 14.9Ab) were not included in the development of the equations because, as described by Ghimire et al. (2019), the bars with large heads exhibited higher anchorage strengths than bars with 9.5Ab and smaller heads. Some headed bars with short embedment lengths ℓeh relative to the distance from the center of the bar to the top of bearing member tended to exhibit low anchorage strengths 266 and were not used to develop the descriptive equations. As demonstrated by Shao et al. (2016), it is more appropriate to evaluate the latter specimens using strut-and-tie models (ACI 318-14). Two specimens in an early test group had no confining reinforcement above or within the joint region and served as trial specimens to provide information for the design of subsequent beam-column joint specimens. Because the lack of confining reinforcement above the joint is inconsistent with design requirements for reinforced concrete columns (ACI 318-14), these specimens were also not used to develop the descriptive equations. The specimens used in the analysis are listed in Table A.2 of Appendix A.* Specimen details are presented in Table A.3 of Appendix A. The measured concrete compressive strengths fcm ranged from 4050 to 16,030 psi (27.9 to 110.6 MPa). No. 5, No. 8, and No. 11 (No. 16, No. 25, and No. 36) headed bars with embedment lengths ℓeh ranging from 3.75 to 19.75 in. (95 to 502 mm) were tested. Center-to-center spacing between the headed bars, cch, ranged from 2.9 to 11.8 bar diameters db. Friction-forged, taper-threaded, and cold-swaged heads, representing a variety of manufacturing processes, were evaluated. Some coldswaged headed bars included in the analysis contained a threaded coupling sleeve adjacent to the bearing face of the head that exceeded the size of obstructions permitted for HA heads in accordance with ACI 318-14 and ASTM A970-13a. As demonstrated by Shao et al. (2016) and later in this paper, these headed bars exhibited anchorage strengths that were similar to those meeting the provisions in ACI 318-14 and were, thus, included in the data used to develop the equations. Details of the heads are provided in Appendix A and by Ghimire et al. (2018, 2019). Three levels of confining reinforcement placed parallel to the bar within the joint region were studied: no confining reinforcement; two No. 3 hoops; and No. 3 hoops spaced at 3db (meeting the requirements for a 0.8 reduction factor for the development length calculation of 90-degree hooked bars in accordance with ACI 318-14, allowing comparisons to be made between hooked and headed bars for a constant amount of joint reinforcement). Bar stresses at failure ranged from 33,100 to 153,160 psi (228 to 1056 MPa). The loading configuration for the beam-column joint specimens is shown in Fig. 1. The headed bars in tension represent the top reinforcement in a beam subjected to negative bending, and the bearing member simulates the compression region of the beam. ANALYSIS OF TEST RESULTS To develop equations that characterize the behavior of headed bars without and with confining reinforcement in simulated beam-column joints, a series of iterative statistical analyses were performed. A least-squares regression technique involving dummy variables was used to determine the effects of key design parameters on the anchorage strength (Draper and Smith 1981). This technique results in a series of parallel lines with different intercepts (Fig. 2) that represent trends in the data.

Descriptive equations of the anchorage strength of headed bars were developed using iterative non-linear regression analyses to ensure a mean test-to-calculated ratio equal to 1.0 while minimizing the sum of the squared differences (1-Test/Calculated)2. Descriptive equations for headed bars without confining reinforcement Widely spaced bars—The descriptive equation for the anchorage strength of headed bars without confining reinforcement is based on test results of the 30 specimens with widely spaced bars (center-to-center spacing ≥ 8db) and is given by Tc = 781fcm0.25ℓeh1.03db0.35 (in.-lb) (3a) Tc = 132fcm0.24ℓeh1.03db0.35 (SI) (3b) where Tc is the anchorage strength of headed bars without confining reinforcement (lb or N); fcm is the concrete compressive strength (psi or MPa); ℓeh is the embedment length (in. or mm); and db is the diameter of the headed bar (in. or mm). Figure 2 compares the ratio of test-to-calculated failure load T/Tc with the concrete compressive strength for the 30 specimens. T is the average bar force at failure calculated at the peak load on the specimen divided by number of headed bars. In Fig. 2, the dummy variable lines are almost horizontal, indicating that Eq. (3) provides a good match with the test results for concrete strengths between approximately 4000 and 16,000 psi (27.6 and 110 MPa). The values of T/Tc range from 0.80 to 1.18, with a mean, standard deviation, and coefficient of variation of 1.00, 0.100, and 0.100, respectively. Equation (3) and Fig. 2 indicate that the anchorage strength of widely spaced headed bars is proportional to the concrete compressive strength to the 0.24 power, rather than ACI Structural Journal/May 2019 Fig. 2—Ratio of test-to-calculated failure load T/Tc versus measured concrete compressive strength fcm for specimens with widely spaced bars and no confining reinforcement. (Note: 1 psi = 0.006895 MPa.) the 0.5 power of compressive strength, as traditionally used in the ACI Code (ACI 318-14). This observation is consistent with the findings by Darwin et al. (1996, 2005) and Zuo and Darwin (1998, 2000) on the splice strength of straight bars and by Sperry et al. (2015a,b; 2017) on the anchorage strength of hooked bars, indicating that concrete compressive strength to a power close to 1/4 provides a superior representation of behavior. Justification for the lower power of compressive strength is provided by the fact that both the bond strength of straight reinforcement and the anchorage strength of hooked and headed bars are governed by the combined effects of concrete tensile strength, which controls initial crack formation and increases with the compressive strength to a power between 1/2 and 2/3, and fracture energy, which controls crack propagation and is independent of compressive strength (Darwin et al. 2001). The overall effect is a power between 0.5 and zero. Equation (3) also indicates that the anchorage strength of headed bars increases almost linearly with the embedment length and that for the same concrete strength and embedment length, larger bars exhibit higher anchorage strengths. The higher strength of larger bars is likely due, at least in part, to the greater effectiveness of the larger heads associated with larger-size bars. The observation that larger headed bars have higher anchorage strengths is also consistent with the observations that larger bars have higher splice strengths than smaller bars for the same splice length (Darwin et al. 1996, 2005; Zuo and Darwin 1998, 2000; Darwin 2005), and larger hooked bars have higher anchorage strengths than smaller hooked bars for the same embedment length (Sperry et al. 2015a,b; 2017). Closely spaced bars—For the 34 specimens with closely spaced bars (center-to-center spacing < 8db), the ratios of anchorage strengths T/Tc (Tc based on Eq. (3)) are plotted versus the center-to-center spacing between the bars in Fig. 3. For comparison, the 30 specimens with widely spaced bars used to develop Eq. (3) are also shown in the figure, represented by open symbols. As shown in Fig. 3, the anchorage strengths of the closely spaced headed bars, regardless of bar size, were generally 267 Fig. 3—Ratio of test-to-calculated failure load T/Tc versus center-to-center spacing for headed bars without confining reinforcement. weaker than those of the widely spaced bars. The trend line for the closely spaced bars shows an increase in anchorage strength with an increase in bar spacing. The value of T/Tc equals 1.0 at a center-to-center spacing of approximately 8db, which is greater than the value of 6db observed for closely spaced hooked bars tested in simulated beam-column joint specimens by Ajaam et al. (2017, 2018). The difference in critical bar spacing between headed and hooked bars is likely due to the geometry of the head; the larger size of the head relative to the bar reduces the effective clear spacing between heads and may result in interaction between headed bars at slightly greater spacings than was observed for hooked bars. Modifying Eq. (3) to account for the effect of closely spaced headed bars results in Eq. (4)   c Tc = (781 f cm 0.24  eh1.03 db 0.35 )  0.0836 ch + 0.3444 (in.-llb) db   (4a) Fig. 5—Ratio of test-to-calculated failure load T/Tc versus head size for specimens without confining reinforcement. with 0.0836(cch/db) + 0.3444 ≤ 1.0   c Tc = (132 f cm 0.24  eh1.03 db 0.35 )  0.0836 ch + 0.3444 (SI) db   (4b) with 0.0836(cch/db) + 0.3444 ≤ 1.0 where cch is the center-to-center spacing between the bars (in. or mm). Figure 4 compares the ratio T/Tc to the concrete compressive strength for the headed bars (both widely spaced and closely spaced) without confining reinforcement, with Tc based on Eq. (4). The slope of the dummy variable lines in the figure indicates that the effect of concrete compressive strength is slightly overestimated by Eq. (4). A slightly lower value for the power of fcm might be more suitable for the combined widely spaced and closely spaced bars, but for simplicity, the 0.24 power for fcm is retained. The ratio T/Tc ranges from 0.68 to 1.27, with a mean, standard deviation, and coefficient of variation of 1.00, 0.111, and 0.111. With the descriptive equations (Eq. (3) and (4)) developed for headed bars without confining reinforcement, the ratios of test-to-calculated failure load T/Tc are plotted versus 268 Fig. 4—Ratio of test-to-calculated failure load T/Tc versus measured concrete compressive strength fcm for specimens without confining reinforcement. (Note: 1 psi = 0.006895 MPa.) head size (net bearing area with respect to bar area) in Fig. 5 for the specimens used to develop the descriptive equations. The slightly negative slope of the trend lines shown in Fig. 5, primarily based on the range of head sizes for No. 8 bars, indicates that the anchorage strength for headed bars without confining reinforcement has a minimal correlation with the head size for heads with bearing areas between 3.8 and 9.5Ab. This, in turn, justifies grouping headed bars with bearing areas from 3.8 to 9.5Ab as a single series for the development of the descriptive equations. Although not covered in this paper, an analysis of a wider range of specimen types indicates that a modification factor of 0.8 should be applied to Tc or Th for headed bars terminating inside a column core (a region of the column cross section located inside the column longitudinal reinforcement) with a clear cover to the bar less than 2.5 in. (64 mm), or terminating in a member other than beam-column joints with clear side cover to the bar less than 8db (Shao et al. 2016). ACI Structural Journal/May 2019 Descriptive equations for headed bars with confining reinforcement Widely spaced bars—For the 43 specimens with widely spaced bars and confining reinforcement within the joint region, the development of a descriptive equation is based on two assumptions: 1) the anchorage strength (Th) is the sum of a concrete contribution Tc, given by Eq. (3), and a contribution from the confining reinforcement within the joint region Ts; and 2) the contribution from confining reinforcement is directly related to an effective quantity of confining reinforcement. Confining reinforcement is considered effective if it is fully anchored, in the form of closed hoops, and is located close to the top of the headed bar—within 8db for No. 3 through No. 8 bars and within 10db for No. 9 through No. 11 bars. These regions match those observed for hooked bars anchored in simulated beam-column joints (Sperry et al. 2015a,b, 2017). The second assumption (dealing with the location of the effective confining reinforcement) is supported by the strain measurements in the confining reinforcement (Shao et al. 2016; Ghimire et al. 2018). The results indicate that the hoops located within the appropriate region (8db or 10db) experienced a significant strain increase at failure (almost all yielded), while the hoops outside this region exhibited much less or a negligible increase in strain. This assumption is also supported by observations of specimens after failure. Most cracks at failure were confined by the hoops that were close to the headed bars, rather than by all the hoops provided in the joint region. Figure 6 shows cracks for a specimen with No. 3 hoops spaced at 3db. The photo was taken after the loose concrete had been removed from the specimen following failure. The specimen contained six hoops within the joint region, but only the top four hoops crossed the major diagonal crack that propagated from the bottom of the head toward the bearing member. The bottom two hoops—one slightly above the top of the bearing member and another slightly below the top of the bearing member (within the compression region)—were below the cracked region. Based on these assumptions and the analysis of the 43 specimens with confining reinforcement, the contribution of confining reinforcement can be expressed as Ts = 48, 800 Ts = 19.5 Fig. 6—Cracks confined by effective confining reinforcement (Specimen 11-5-F3.8-6#3-i-2.5-3-12). No. 11 (No. 29 through No. 36) headed bars (N); n is the number of headed bars; and db is the diameter of headed bar (in. or mm). The term Att/n is the area of confining reinforcement per headed bar with an upper limit of 0.3Ab. Equation (5) indicates that the anchorage strength of headed bars is proportional to the amount of confining reinforcement parallel to the bar and to the bar diameter to the power 0.88. The fact that db appears in the equation indicates that a given quantity of confining reinforcement is more effective in increasing the anchorage forces as the size of the headed bar increases. These observations are, in general, consistent with the contribution of confining reinforcement parallel to hooked bars as expressed in Eq. (6) (Sperry et al. 2017). The power of 1.06 on the confining reinforcement term Ath/n is close to 1.0, signifying a linear relationship between the anchorage strength of hooked bars (Ts) and confining reinforcement Att 0.88 db (in.-lb) n (5a) A  Ts = 54,250  th   n  Att 0.88 db (SI) n (5b) A  Ts = 37.6  th   n  where Ts is the contribution of confining reinforcement to the anchorage strength of a headed bar (lb or N); Att is the total cross-sectional area of effective confining reinforcement parallel to the headed bars being developed (in.2 or mm2), which is the product of the cross-sectional area of a single leg of confining reinforcement (Atr,l) and the total number of single legs of confining reinforcement parallel to the straight portion of a headed bar within 8db from top of headed bar for No. 3 through No. 8 (No. 10 through No. 25) headed bars and within 10db from top of headed bar for No. 9 through ACI Structural Journal/May 2019 1.06 db 0.59 (in.-lb) (6a) db 0.59 (SI) (6b) 1.06 where Ath is the total cross-sectional area of effective confining reinforcement parallel to the hooked bars being developed (in.2 or mm2), analogous to Att for headed bars. Combining Eq. (3) with Eq. (5), the anchorage strength for widely spaced headed bars with confining reinforcement can be expressed as Th = 781 f cm 0.24  eh1.03 db 0.35 + 48, 800 Att 0.88 db (in.-lb) (7a) n 269 Fig. 7—Ratio of test-to-calculated failure load T/Th versus measured concrete compressive strength fcm for specimens with widely-spaced bars and confining reinforcement.

T is the average peak load. Th is based on Eq. (7). The slope of dummy variable lines in the figure indicates that the effect of concrete compressive strength is slightly underestimated by Eq. (7). The values of T/Th range from 0.81 to 1.20, with a mean, standard deviation, and coefficient of variation of 1.00, 0.095, and 0.095, respectively. Closely spaced bars—For the 31 specimens with closely spaced bars and confining reinforcement, the ratios of anchorage strengths T/Th, with Th based on Eq. (7), are plotted versus the center-to-center spacing between the bars in Fig. 8. The 43 specimens with widely spaced headed bars used to develop Eq. (7) are also shown in the figure, represented by open symbols. Like the closely spaced headed bars without confining reinforcement, Fig. 8 shows that the closely spaced bars with confining reinforcement generally exhibited lower anchorage strengths than the widely spaced bars. The trend line, however, is flatter than that shown in Fig. 3, indicating that the anchorage strength of headed bars with confining reinforcement is affected less by close bar spacing than that of headed bars without confining reinforcement. Of the 31 specimens with closely spaced bars and confining reinforcement, 14 had two No. 3 hoops and 17 had No. 3 hoops at 3db.

Figure 9 compares the ratio T/Th with concrete compressive strength for the headed bars (both widely spaced and closely spaced) with confining reinforcement, with Th based on Eq. (8). The slope of dummy variable lines in the figure indicates that the effect of concrete compressive strength is slightly underestimated by Eq. (8). The ratio T/Th ranges from 0.81 to 1.24, with a mean, standard deviation, and coefficient of variation of 1.00, 0.095, and 0.095, respectively. With the descriptive equation (Eq. (8)) developed for headed bars with confining reinforcement, the ratios of test-to-calculated failure load T/Th are plotted versus head size in Fig. 10 for the specimens used to develop the descriptive equations. The closely spaced, slightly upward trend lines shown in Fig. 10 indicate that within a range of 3.8 to 9.5Ab, head size has a minimal influence on the anchorage strength for headed bars with confining reinforcement. As was found for specimens without confining reinforcement, this result justifies treating headed bars with 3.8 to 9.5Ab heads as a single series for the development of the descriptive equations. In Fig. 11, the failure loads T for all specimens are compared with the values of calculated failure load Th ACI Structural Journal/May 2019 Fig. 10—Ratio of test-to-calculated failure load T/Th versus head size for specimens with confining reinforcement. obtained using the descriptive equations, Eq. (4) and (8). As shown in the figure, the descriptive equations slightly overestimate the anchorage strength for No. 5 bars and slightly underestimate the anchorage strength for No. 11 bars. The variation, however, is small given the range of data. Headed bars with large obstructions The anchorage strengths of headed bars with cold-swaged threaded coupling sleeves with obstructions exceeding the dimensional limits for HA heads in ASTM A970-13a (heads permitted by ACI 318-14) O4.5 and O9.1, were compared with the anchorage strengths of the headed bars meeting the requirements. The net bearing area of the large obstruction heads is taken as the difference between the gross area of head and the area of the obstruction adjacent to the head. The dimensions of the heads and obstructions are shown in Appendix A. Twenty-two specimens contained headed bars with large obstructions with net bearing areas of 4.5 and 9.1Ab. Of the 22 specimens, 14 had no confining reinforcement and eight had confining reinforcement within the joint region parallel to the headed bar. For the 14 specimens without confining reinforcement, the ratio of test-tocalculated failure load T/Tc ranged from 0.90 to 1.27, with a mean, standard deviation, and coefficient of variation of 1.01, 0.107, and 0.106, respectively. For the remaining eight specimens with confining reinforcement, the ratio of test-to-calculated failure load T/Th ranged from 0.90 to 1.17, with a mean, standard deviation, and coefficient of variation of 0.99, 0.089, and 0.090, respectively. This indicates that the headed bars with large obstructions have similar anchorage strengths to those that met the requirements of HA heads in ASTM A970-13a and can be safely used in design. These observations were used to modify the criteria for the size of obstructions and are now permitted for HA heads by ASTM A970-18. SUMMARY AND CONCLUSIONS Descriptive equations for the anchorage strength of headed bars in concrete were developed. The descriptive equations account for the effects of concrete compressive strength, embedment length, bar size, spacing between the ACI Structural Journal/May 2019 Fig. 11—Test failure load T versus calculated failure load Th for specimens without and with confining reinforcement. Th is calculated based on Eq. (4) and (8). (Note: 1 kip = 4.448 kN.) bars, and confining reinforcement. Results from 138 beamcolumn joint specimens, 64 without and 74 with confining reinforcement within the joint region, were used to develop the equations. No. 5, No. 8, and No. 11 (No. 16, No. 25, and No. 36) headed bars with embedment lengths ranging from 3.75 to 19.75 in. (95 to 502 mm) were tested in concrete compressive strengths ranging from 4050 to 16,030 psi (27.9 to 110.6 MPa). Center-to-center spacing between the headed bars ranged from 2.9 to 11.8 bar diameters. Bar stresses at failure ranged from 33,100 to 153,160 psi (228 to 1056 MPa). Some headed bars contained obstructions adjacent to the head that exceeded the dimensions permitted for HA heads in ACI 318-14 and ASTM A970-13a but are now permitted by ASTM A970-18. The following conclusions are drawn based on the results presented in this paper. 1. The effect of concrete compressive strength on the anchorage strength of headed bars can be represented by the compressive strength to the 0.24 power, which is close to the relationship for the development length of straight bars and the anchorage strength of hooked bars. 2. Anchorage strength is improved by the addition of confining reinforcement parallel to the headed bar, a factor that is not included in current design provisions; the increase in anchorage strength is proportional to the amount of confining reinforcement per headed bar within eight to 10 bar diameters of the headed bar. 3. For a given embedment length, the anchorage strength of headed bars increases with an increase in bar diameter. 4. The anchorage strength of headed bars begins to decrease as the center-to-center spacing between the bars decreases below eight bar diameters, another factor not included in current design provisions. 5. Headed bars with obstructions larger than permitted in ACI 318-14 and ASTM A970-13a that meet the new provisions in ASTM A970-18 exhibit similar anchorage strengths to those that meet the provisions in ACI 318-14.
