Among the different lateral force resisting systems, shear walls are of appropriate stiffness and hence are extensively employed in the design of high-rise structures. The architectural concerns regarding the safety of these structures have further widened the application of coupled shear walls. The present study investigated the optimal dimensional design of coupled shear walls based on the im...

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...

A common lateral force resisting system for cold-formed steel (CFS) buildings consists of shear walls sheathed with oriented strand board (OSB). Previous experimental and computational research on CFS shear walls, as well as those with other framing materials, has demonstrated that the complex interaction of the fasteners with the sheathing is an important factor in the nonlinear behavior of th...

In order to meet the needs of performance-based seismic design, a new type of adaptive-slit shear wall that is easy to construct and behaves well under cyclic loading is introduced to improve the seismic performance of conventional shear wall structures. The seismic damage of an adaptive-slit shear wall develops gradually and it transforms from integral wall into slit wall. The mechanical chara...

In this paper, nonlinear behavior of strengthened steel plate shear walls (SPSWs) by FRP laminates theoretically and numerically has been investigated. In the first part, a new method, “the composite-plate frame Interaction (C-PFI) method”, has been introduced to predict the shear behavior of the composite steel plate shear wall systems (CSPSWs). In the second part, several models of one-story ...

To study mechanical behaviors of shear walls built with precast two-way hollow slabs, two shear walls with different details of hollow slabs were quasi-statically tested under low cyclic loading. The failure mode was analyzed, which vertical macro-cracks appeared on walls due to the details of hollow slabs. Brittle shear failure can be avoided in terms of the failure behaviors evolved from inte...

A revised procedure for the design of steel plate shear walls is proposed. In this procedure the thickness of the infill plate is found using equations that are derived from the plastic analysis of the strip model, which is an accepted model for the representation of steel plate shear walls. Comparisons of experimentally obtained ultimate strengths of steel plate shear walls and those predicted...
