摘　　要：文章以某带端部转换高层剪力墙结构为例,进行了多遇地震下不同力学模型的弹性计算和罕遇地震下的弹塑性分析,对转换部位侧向刚度进行对比研究,并对单榀框支转换部位构件进行在竖向恒载和水平地震作用下的平面有限元分析,对其应力分布情况进行了探讨。结果表明,结构整体和转换部位具有较好的承载和变形能力,可供同类工程参考。Taking a high-rise shear wall structure with end transformation as an example, the elastic calculation in different mechanical models under frequent earthquake and the elasto-plastic analysis un- der rare earthquake are performed, and the contrastive study of the lateral stiffness of the transforma- tion site is made. Then the plane finite element analysis of the single cross component of the transfor- mation part under vertical constant load and horizontal seismic force is carried out, and the stress dis- tribution of it is discussed. The results show that the whole structure and the transformation part have good bearing and deformation capacities. The study can provide a reference for similar projects.
