摘　　要：利用有限元数值模型分别计算了四边简支和四边固支均匀受剪矩形板弹性屈曲剪应力及屈曲后极限强度。考虑内填板的屈曲后强度,通过相关文献的单层和4层钢板剪力墙试验数据验证了多层钢板剪力墙有限元数值模拟方法的正确性。利用试验验证的有限元分析方法分别研究了单层和4层钢板剪力墙在水平荷载作用下内填板高厚比的变化对结构性能的影响,并与相应的单层和4层纯框架结构进行了比较,这为钢板剪力墙在不同阶段的结构性能分析提供了依据。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.
