组合结构的抗震性能分析

Analysis of Seismic Performance for Composite Structures

运用SAP 2000有限元结构分析软件建立结构的线性三维模型,并分别对加层有支撑的组合结构模型及加层无支撑的组合结构模型进行了分析。通过对比两种结构在模态分析和振型反应谱分析下得到的关于自振周期、楼层位移和层间剪力的数据,得出了相关结论。结论表明:加层有支撑的组合结构抗震性能优于加层无支撑的组合结构。

The authors used a finite element analysis software SAP 2000 to establish 3d model for a structure and the combination of the support structure model for coating layer and an unsupported combination structure model were analyzed. By comparing the two kinds of structures in modal analysis and vibration modal response spectrum analysis of natural vibration period, under the floor displacement, lnterlaminar shear data was obtained, and the relevant conclusions were drawn. The results indicated that seismic performance for add layer with the combination of the support structure was superior to add layer without the combination of the support structure.
