Confined masonry consists of no reinforced masonry walls surrounded by concrete tiecolumns, in the vertical direction, and tie-beams, in the horizontal direction. In some countries confined masonry walls may include joint reinforcement. Although confined masonry structures are still a common masonry construction system in several countries, the majority of them are built using plain masonry. All load-bearing walls in confined masonry constructions must be confining on all sides with horizontal and vertical confining elements. The goal of this research is to use a numerical analysis method using ANSYS software package to evaluate the impact of confining elements such as tie-columns, in-plan walls, and out-plan walls on resisting horizontal lateral loads. Finally, results and conclusions were provided from different finite element analysis models of confined masonry buildings with various confining element configurations.

Confined masonry (CM) is considered one of the popular forms of low-cost and low-rise construction throughout the world. Confined masonry consists of non-reinforced masonry walls surrounded by concrete tie-columns, in the vertical direction, and tie-beams, in the horizontal direction. In some countries confined masonry walls may include joint reinforcement. The behavior of constrained masonry structures under cyclic lateral loads was investigated in this experimental research. The two-story half-scale model was made using local materials and standards in consideration. With increasing displacement, lateral cyclic loads were applied to the model. Crack pattern, failure mechanism, lateral capacity, energy dissipation, ductility, and overall structural performance were all evaluated. Out of plane walls provided additional restrictions for wall movements and increased structural performance, while masonry infill walls provided significant strength and ductility. The findings show that confined masonry structures constructed to the standard will withstand the design lateral loads successfully. The case study for the tested assembly was verified using finite element model verification using experimental results. The developed model is capable of accurately capturing the maximum load and its related deformation of the tested structure, according to the results of the finite element analysis. For fracture patterns and failure mechanisms, the suggested model agrees well with the results of laboratory tests.
