平面L形钢结构的抗震性能分析

Analysis of Seismic Performance of L-shaped Steel Structure

利用SAP2000结构分析软件建立有支撑的平面L形钢结构建筑和无支撑的平面L形钢结构建筑两种结构的分析模型,通过对两种结构的模型进行周期分析、双向振型反应谱分析和时程分析,得到了两种结构模型关于层间位移、层间位移角等的数据信息,并进行了对比,从而得出相关结论.结果表明:有支撑的平面L形钢结构建筑较无支撑的平面L形钢结构建筑抗震性能好.

This paper uses the structural analysis software SAP2000 to set up the models of supported L-shaped steel structure and unsupported L-shaped steel building model. By means of executing the natural vibration period,vibration modal response spectrum analysis and elastic time-history analysis on the above two mentioned structure models,the inter-layer displacement,angle displacement and other data information between the layers of the above two structure modals were obtained and the relevant conclusions were drawn. The result show that there is a better seismic performance of the supported L-shaped steel structure than the L-shaped steel structure which is not supported.
