【摘要】 湖北省图书馆新馆为特别不规则的多项超限复杂高层建筑。根据本工程的结构特点,有针对性地选择了抗震性能目标,采用基于性能的抗震设计方法,对该结构进行了抗震设计。通过采用SATWE和MIDAS软件,分别进行小震作用下静力和弹性时程分析、中震作用下特别重要构件的弹性设计及其它构件不屈服判别分析、大震作用下静力弹塑性推覆(Pushover)分析,找到了结构抗震薄弱部位,采取了对应的抗震加强设计。最后的计算结果表明,该工程的结构抗震设计及采取的抗震加强措施能满足抗震设防要求,其抗震设计理念对类似建筑具有较好的参考价值。更多还原

【Abstract】 Hubei Library New building is a complex tall structure with many items exceedings pecification of code limit.According to the structural characteristics of this project,the suitable seismic performance objectives to the project is selected,and performance-based seismic design method is used.By study the results of static analysis and time history analysis under frequent earthquake,elastic design of especially important members and yielding identification analysis under moderate earthquake,static pushover analysis under rare earthquake from SATWE,MIDAS,weak portions of the structure are found,and specific seismic measures are used to strengthen the structure.The final results show that the structural seismic design with strengthening measures can meet seismic performance requirements.The aseismatic design concept of this building has good reference value for similar projects.更多还原
