摘要
采用有限元软件ANSYS,并结合具体工程实际对砖混结构顶部钢结构加层建立了三维有限元模型,采用振型分解反应谱法和时程分析法进行了多遇地震作用下结构的地震反应分析,得到了该结构的自振周期、振型特点、位移分布及加层前后的底层层剪力,为该类结构的抗震设计提供了一些有意义的结论。
In this paper, a three-dimensional adding steel stories on top of the multistoried brick-eoncrete architecture is made by the large general structure analysis software ANSYS. The dynamic characteristics and the seismic responses are obtained by using response spectrum method and time history analysis method; the results are compared and studied which can be served as the basic of such structure design.
