As we move vertically up in the design of skyscraper the main problem which concern are changes from the gravitational loads to the lateral loads. Diagrid is a form of a perimeter grid which is made up of a series of triangulated truss generated by intersecting the diagonal and horizontal members. The present research study is an attempt to understand the behaviour of the diagrid system in the circular edifice. A circular plan of the edifice is created for this research study of g+16 storeys with diagrid system at the outer periphery having an angle of 430 and the diagrid is formed for each story. IndexTerms Seismic analysis, RC Circular Frame, Diagrid structure, Comparative study, Software based analysis.

The ABAQUS software is used for the analysis. Eight-Node Shell element with five degrees of freedom (S8R5) is used throughout the analysis. Five different types of layup sequences of the laminate combined with five different types of loading are considered for the analysis. Two different types of material have also been used. Five different skew angles have been used to analyze the buckling behavior under different loading conditions. Comprehensive results have been obtained in this study which is presented accordingly. IndexTerms – Laminate, Composite, Plate, Cut-out, ABAQUS, Buckling load, Skew.

Millions of lives have gone because of this disaster. Though it cannot be stopped but through various measures, lives and resources can be saved. Especially through following certain preventive measures as per scientific standards, its effects can be minimized or prevented. Buildings are on great risks because of the earthquakes. When a multi-storied building falls down, it takes many lives with it. In addition, removing the rubbles will cost a lot. Rather, constructing a building which can endure these earthquakes is the most ideal step to take. There are many scientific guidelines as per which a strong multi storied building can be constructed. This project involves the analysis of simple 2-D frames of varying floor heights and varying number of bays using a very popular software tool Etabs. Using the analysis results reaction, displacement, shear in column and beam is obtained. In addition to that the detailed study of seismol...

Cloud computing is a set of possessions and services that are on hand by the network or internet. Cloud computing extend a variety of computing techniques like grid compute, distributed computing. Today cloud computing is used in both industrial pasture and educational field. As the meadow of cloud computing is scattering the new technique are increasing. This amplifies in cloud computing location also increases security challenges for cloud developers. Users of confuse save their data in the shade hence the lack of security in cloud can lose the user’s trust. In this paper we will discuss some of the cloud security issue in a mixture of aspects like multi-tenancy, stretch, accessibility etc. the paper also argue existing security technique and approaches for a protected cloud.

Furthermore, the structures utilizing concentrated steel bracings framework are utilized for similar reasons in steel structures. Both of the frameworks have meaning of the primary presentation. Albeit the two frameworks are utilized for same the reasons, their impact shows inconsistent varieties and conduct against seismic burden. This is for the explanation that the estimations of reaction factors are random for fluctuating primary frameworks. This examination contains a mathematical way to deal with show disparity between the shear divider framework and steel supporting framework. Tremor is the characteristic disaster, it produce solid ground movements which influence the design. Little or frail movements that can or can't be felt by the people. Arrangement of shear dividers and bracings are introduced to can improve the horizontal firmness, flexibility, least sidelong relocations and wellbeing of the design. Story float and horizontal removals are the basic issues in seismic plan of structures.

This proposed procedure reveals the effects of soil-foundation-structure interaction on the seismic response. Soil-foundation-structure interaction provisions of seismic design codes are optional and allow designers to reduce the design base capacity of buildings by considering soil-structure interaction (SSI) as a beneficial effect. The soil-structure system can be replaced with an equivalent fixed-base model with a longer period and usually a larger damping ratio. Spread foundation, mono pile, pile group with cap, and combined foundation are the four types of foundations were analyzed, with frequency-based design. Implicitly (subgrade reaction modulus) and explicitly both are used to model the soil. STAAD Pro program used with finite level model were the first validation using experimental data. Recommendations were given to simplify the soil-foundation structure interaction analysis of seismic loading. Differe...

Hydrotreating is an important unit operation in petroleum refining. 1 Its importance is further emphasized by the stringent sulfur specifications of petroleum products needing ultra low sulfur fuels in the range 10-15 ppm. 2 On board fuel cells also require fuels with sulfur as low as 0.1 ppm. Calculations revealed that in order to produce such a low sulfur fuel, seven times more active catalysts are needed. Many approaches such as method of preparation of catalysts, variation of promoters or variation of supports are employed towards this end. Among these, variation of the support is an important one. 3-5 Many materials have been tested as supports for Mo with Co or Ni as promoters, some of which are SiO 2 , Al 2 O 3 , MgO, ZrO 2 , TiO 2 , carbon, mixed oxides such as TiO 2-ZrO 2 , ZrO 2-Al 2 O 3 , TiO 2-Al 2 O 3 , ZrO 2-SiO 2 , SiO 2-Al 2 O 3 , TiO 2-SiO 2 etc. Zeolites such as NaY, USY, b-zeolite have also been employed as supports. In recent years mesoporous materials 3,4,6,7 such as MCM-41, SBA-15, 8,9 and HMS 10 have been studied with great interest as supports for hydrotreating catalysts due to their high surface area, stability, and well defined pores with narrow size distribution. FSM-16 materials, which are analogous to MCM-41 (hexagonal, p6mm) materials, have gained much attention because of their high surface areas and pore volumes. To our knowledge there is no detailed report on FSM-16 supported molybdenum catalysts for hydrotreatment. Herein, we are reporting for the first time the outstanding activities of FSM-16 supported molybdenum catalysts promoted with cobalt and nickel for hydrotreating reactions. The FSM-16 material is prepared by a method similar to that used by Inagaki et al. 7 A typical synthesis procedure is as follows: 30 g of kanemite was dispersed in 300 ml of water and then stirred for 3 h at 300 K.
