摘要
为研究钢交错桁架结构在地震作用下的动力特性,在现有动力计算模型的基础上,提出一种用于研究该结构横向抗震性能的新模型——伪空间模型。基于提出的伪空间模型,运用有限元分析软件SAP2000,进行相应的模态分析和静力弹塑性分析,并与空间模型的计算结果进行了比较。分析结果表明伪空间模型可以较好的模拟钢交错桁架结构的横向抗震性能。
A pseudo-space model is proposed to assess the transverse seismic performance of steel staggered truss. Modal analysis and pushover analysis have been performed with SAP2000 to the space model, plane model and pseudo-space model of steel staggered truss structure. By comparing the response of models, it shows that the pseudo-space model is appropriated to analyze the transverse seismic performance of steel staggered truss structure.
