弹性时程分析的应用体会

Application Experience of Elastic Time-History Analysis

根据《建筑抗震设计规范》GB50011—2010的有关规定,特别不规则的建筑、甲类建筑以及超过一定限制的高层建筑应进行多遇地震下的弹性时程补充分析。新版的结构设计软件(YJK1.8版及PKPM2010V3.1版)提供了足够多的地震波,软件能够自动筛选符合指定条件的地震波。论文通过工程实例,详细介绍了如何应用PKPM及YJK软件进行时程分析,以及对时程分析的结果如何使用,并重点指出了时程分析时需要注意的几个问题,供同类工程参考。

According to the relevant provisions of the Code for seismic design of buildings GB 50011—2010, for buildings having extremely irregular configuration, buildings assigned Fortification Category A, and tall buildings within the certain height range, an elastic time-history analysis method under frequently earthquake shall be used as an additional computation. Structure design softwares（YJK1.8 and PKPM2010 V3.1） provides enough seismic waves, the softwares can automatically screen seismic waves that meet the specified conditions. The paper introduces how to use PKPM and YJK softwares to proceed the analysis, and how to use the results of time history-analysis through an engineering example, and points out some problems that should be noticed in time history-analysis, for reference of similar projects.
