变电站RC框架结构基于中震下不同性能目标设计方法探讨

Discussion on the Design Method of RC Frame Structure of Substations Based on Different Seismic Performance Objectives under Moderate Earthquake

变电站是一定区域内的电力供应中心，提高其建筑抗震设防能力意义重大。针对我国抗震规范中没有给出对中等地震的具体的设防目标和性能水准的问题，提出了“中震轻微损坏”和“中震中等破坏”两个性能目标以及相应的性能指标．给出了利用SATWE软件基于这些性能目标进行变电站RC框架结构设计的方法，并利用时程分析验证了所提设计方法的可行性。

A transformer substation is the power center of certain area, and thus it is important to improve its seismic capacity. Aiming at the problems that the Seismic Code （GB50011-2001） does not give the specific and quantitative performance index against moderate earthquake, this paper proposes two performance objects of ＂slight damage＂ and ＂medium damage＂ and relative performance indexes under moderate earthquake, and proposes the design method of RC frame structure of substations based on these seismic performance objectives by using SATWE software, and veryfies the feasibility of the proposed method with time-history analysis.
