温州某中学项目结构抗震设计

Seismic Design of a Middle School Building in Wenzhou

文章以温州市某中学为例,对其存在的扭转不规则、凹凸不规则、楼板不连续等情况,在设计时采用PKPM结构设计软件对结构抗震性能进行分析,以YJK软件进行计算结果对比;同时对结构进行了小震反应谱和弹性时程分析、大震弹塑性分析和抗震性能化设计。结果表明,结构的整体抗震性能可以达到设计的C级性能目标的要求。

The project is a middle school in Wenzhou.Several irregular aspects exist in this building, such as irregular torsion, concave-convex structure plan, discontinuous floor.During the design,PKPM structure design software is used to analyze the seismic performance of the structure, supplemented by YJK software to compare the calculation results. The response spectrum analysis and elastic time-history analysis of small earthquake,elastic-plastic analysis of rare earthquake, and performance-based seismic design are carried out.The results show that the overall seismic performance of the structure can reach the requirements of the class C performance target.
