摘要
应用弹塑性计算方法对汶川地震遭受损害的什邡电信大楼进行推覆分析,研究该结构在罕遇地震作用下的内力、变形与破坏情况。比较该结构在不同加载模式下的抗震性能,从而判定结构在罕遇地震作用下是否满足不倒塌的抗震设计目标。通过SAP2000软件辅助计算深入理解静力弹塑性计算方法并将计算方法延伸到更加复杂的结构抗震设计中。
Shifang telecom building which suffered from the Wenchuan earthquake is analyzed by applying pushover method, the deformations, internal forces, and damage patterns of the structure under the rare earthquake are studied, the different loading patterns of the structure are compared, then seismic resistance of the mode is evaluated, at last the recommendations of the seismic retrofitting are made. By finite element software SAP2000, the intuitive and in-depth understanding of static elasto-plastic method is obtained, then the calculating method can be oxtended to more complicated seismic design.
