摘要:
探究高层建筑桁架转换层地震作用下的动力反应情况，采用SAP2000程序中平面壳单元和杆系单元对高层建筑桁架转换层进行有限元建模，采用模态分析法和地震反应谱分析法对高层建筑桁架转换层结构进行地震反应分析，结果表明：高层建筑中桁架转换层前8阶振型对自振周期影响较大，分析高层建筑桁架转换层地震作用反应时，主要采用前8阶振型振型，且桁架转换层及其上、下层间容易出现层间位移角突变现象，桁架转换层极易发生位移集中，是高层建筑的脆弱部分，应加强高层建筑桁架转换层设计，提升建筑安全性。
Abstract:
In order to explore the dynamic response of the truss transfer floor of high-rise building under earthquake, the paper builds the finite element model of the truss transfer floor of high-rise building by using the plane shell element and the bar system element in SAP2000 program, and analyzes the seismic response of the truss transfer floor of high-rise building by using modal analysis method and the seismic response spectrum analysis method. The results show that the first eighth order mode shapes of truss transfer floor in high-rise buildings have a great influence on the natural vibration period. When analyzing the seismic response of truss transfer floor in high-rise buildings, the first eighth order mode shapes are mainly used, and the sudden change of story displacement angle is easy to occur between the truss transfer story and its upper and lower layers. The truss transfer floor is the vulnerable part of high-rise buildings, and it is necessary to strengthen the design of high-rise building truss transfer floors to improve building safety.
