摘　　要：本文通过对一幢带高位转换层的某高层框支剪力墙结构工程实例的分析,采用SATWE软件建立普通转换梁结构模型与宽扁梁转换结构进行对比。从结构整体受力、多遇地震下弹性反应出发,较详细的分析宽扁梁转换结构的抗震性能。然后运用EPDA软件对宽扁梁高位转换结构模型进行罕遇地震下静力弹塑性分析,得出推覆过程中结构基底剪力-顶点位移曲线和层间位移角等数据。通过控制结构抗震性能点,找出薄弱部位,对结构抗震性能进行综合评价,供同类型结构的抗震设计参考。Combining a frame‐supported shear wall structure with high‐level transfer floor ,two differ‐ent structure models of the wide‐flat transfer beam model and common transfer beam model have been built by using SATWE .A detailed anti‐seismic performance analysis of the wide‐flat transfer beam model has been established through w hole structure stress analysis ,small elastic seismic response a‐nalysis ,respectively .Then a static elasto‐plastic analysis has been applied on the high‐level transfer structure model with the wide‐flat transfer beam to provide the date of the base shear‐top displacement cure and the interlayer displacement angle .Through the control of structural seismic performance ,the comprehensive evaluations of structural seismic performance have been given .T he research results can be used as references for the seismic design of the same type of structure .
