FINITE ELEMENT ANALYSIS FOR PERFORMANCE OF MULTI-STOREY STEEL PLATE SHEAR WALLS SUBJECTED TO HORIZONTAL LOAD

Elastic buckling shear stress and post-buckling ultimate capacity of all edges simply supported plate and all edges clamped rectangular plate subjected to pure uniform shear forces are analyzed by using the finite element model, respectively. The effectiveness of multi-storey steel plate shear wall (SPSW) model accounting for the post-buckling strength is demonstrated by comparing the predicted response with results from experimental studies performed by other researchers. The effect of different slenderness ratios on the behavior of single-storey and four-storey SPSW subjected to horizontal monotonic load is obtained by the verified analytical model, which is compared with the performance of the corresponding bare frames. Many good conclusions presented can provide the fundamental reference for detailed structural performance of SPSW in the different stress phases.
