In tall buildings the reinforced concrete (RC) shear wall is one of the predominant structural components used to resist lateral loads induced by earthquakes around the world. Previous research demonstrated that shear walls displayed a sudden loss in lateral capacity due to the wall corner and web crushing in the plastic zone. In addition, it was found that large shear distortions in shear wall...

concrete shear walls are the most prevalent structural systems resisting lateral loads due to earthquakes in high-rise buildings. very large in-plane stiffness of shear walls provides an excellent drift control in the structure. however, structural damages and early code shortcomings threaten the efficiency of existing structural walls against earthquake. recently, fiber reinforced polymer (frp...

The seismic performance of recycled aggregate concrete (RAC) composite shear walls with different expandable polystyrene (EPS) configurations was investigated. Six concrete shear walls were designed and tested under cyclic loading to evaluate the effect of fine RAC in designing earthquake-resistant structures. Three of the six specimens were used to construct mid-rise walls with a shear-span ra...

In most cases, structural engineers assume a concrete floor to be a rigid diaphragm. Although this simplification is in most cases acceptable, it should be noted that such an assumption may be distrusted due to certain problems. Concrete structures with staggered shear walls are among those whose analysis should be conducted with special concern for the behavior of their floor diaphragms. Howev...

In this study, the cyclic behaviors of low rise concrete shear walls using recycled coarse or fine aggregates were investigated. Eight low rise Recycled Aggregates Concrete (RAC) shear wall specimens were designed and tested under a cyclic loading. The following parameters were varied: replacement percentages of recycled coarse or fine aggregates, reinforcement ratio, axial force ratio and X-sh...

verifying the behavior of shear walls in a tall building requires reliable response results. this paper examined nonlinear fiber element modeling of a slender reinforced concrete shear wall during large-scale shaking table testing. the goal was to understand and validate the inelastic responses given by fiber models using time history analysis. reasonable agreement was found between the numeric...
