摘要
选用有限元软件SAP2000,结合实际工程对砖混结构顶部轻钢直接加层建立了三维有限元模型,应用振型分解反应谱法对结构的抗震性能进行分析,获取了该结构动力特性和其在多遇地震作用下的地震响应,为类似结构形式的设计提供一定的参考价值.
In this paper,by using finite-analysis software SAP2000,a three-dimensional model is estab-lished to analyze the multistoried brick-concrete architecture of adding steel stories on its top.The seismic performance is analyzed by using response spectrum analysis,and the dynamic behavior and the seismic response features about storey-adding of light-weight steel structure is obtained, which offers reference for the design of similar structures.
