|
摘要
结合中国科学技术馆新馆的工程特点,对该复杂结构设定抗震性能目标,并针对性能目标提出抗震措施及抗震构造措施。考虑结构材料的非线性,采用动力非线性分析方法,分析框架-剪力墙结构在地震作用下的动力响应,并对关键部位进行罕遇地震下承载力及耗能专项分析。结果表明,结构在罕遇地震下满足规范要求,关键部位可以实现罕遇地震下不屈服的要求,结构是安全可靠的。
According to the characteristics of new China Science and Technology Museum,the goal of seismic design was proposed for the complicated structure.Dynamic nonlinear analysis was adopted considering the nonlinear property of materials.Dynamic response of the frame-shear wall structure under earthquake was carried out,and the bearing capacity and energy dissipation capacity of key parts under rare earthquake were analyzed.The results show that the structure can satisfy the code requirements,the key parts do not yield under rare earthquake,and the structure is safe and reliable.
