Investigating the Behavior of Coupled Steel Plate Shear Wall under Cyclic Loading

چکیده مقاله

Using resistant systems in construction industry is essential to reduce the damages caused by earthquake loads. One of the most suitable resistant systems is steel plate shear wall with a coupling beam (Coupled Steel Plate Shear Wall or CSPSW), which comprises horizontal boundary elements (beams), vertical boundary elements (columns) and steel plate. In this study, the behavior of CSPSW under the effect of cyclic loading in three (six-, eight- and twelve-story) frames for three different lengths of coupling beam has been investigated in OpenSees. In the first part of this study, the structure responses including shear capacity, flexural capacity, energy dissipation, ductility of shear wall and coupling beam, and rotation created in coupling beam are investigated. The results indicated that the effect of coupling beam length on the performance of the components of the CSPSW is different, in a way that as the coupling …
