摘　　要：运用SAP2000程序对楼板开大洞框支剪力墙实际工程结构进行了空间有限元分析,研究了这种结构的动力特性以及在三种地震波输入下的加速度反应、位移反应和地震力分布,并对其抗震性能进行了评价。研究成果对类似工程结构设计有一定的指导意义。In this paper, the threedimensional finite element program-SAP2000 is used to analyze an actual structure, which is a frame supported shear wall tall building with big openings in floor. Based on the space finite element analysis model, we have studied the natural vibration characters of the building . By use of the recorded data of three earthquake waves and the time history method, the seismic responses of the structure,such as acceleration responses,displacement responses and the distribution of the seismic forces,are discussed respectively. The earthquake resistant capacity of the building is evaluated .Some suggestions are given for engineering design of this type of structures.
