【摘要】 根据高层钢结构在抗侧方面能力的不足,对于双塔大底盘结构,可考虑抗侧力由偏心耗能支撑提供。论文运用有限元分析软件SAP2000对两种不同的结构方案分别进行双向水平地震作用下的时程分析。根据两个方案的结构动力特性结果,得到一个合理的方案。更多还原

【Abstract】 According to the shortage of the lateral resistant capacity in the high-rise steel structure,the lateral resistant force of the double tower large foundation structure could be considered to be provided with the eccentric energy consumption support.The finite element analysis software SAP2000 was applied to the time-history analysis on the two different structural plans individually under the double direction horizontal earthquake role.According to the results of the structural dynamic features for the two plans,a rational plan was obtained.更多还原
