摘　　要：结合工程实例,采用SAP2000中的框架单元和分层壳单元对进水塔结构进行Pushover分析和比较,表明两种单元均能较好的模拟结构的弹塑性特性;通过对Pushover分析与非线性时程分析结果的对比,发现两种方法的计算结果能吻合较好,所以Pushover方法可以对进水塔结构在罕遇地震作用下的抗震性能做出合理的评价。Combining with the project examples,the Pushover analyses are used for analying and comparing an intake tower by using the frame element and layered shell element in SAP2000 respectively.The results indicate that both models could simulate the elastic-plastic properties of intake towers properly.Comparing the results of Pushover analysis with those of nonlinear time-history analysis,it is found that the results of these two methods could agree well mutually.So the reasonable evaluation on the aseismatic capacity of intake towers could be achieved by Pushover analysis.
