［摘要］中国建设银行股份有限公司宁波市分行新综合业务楼为采用框架-剪力墙结构体系的特别不规则结构。介绍了该结构的超限设计，包括小震反应谱分析、弹性时程分析和Pushover分析，对关键构件提出合适的性能目标，采取了相应抗震加强措施。对关键钢桁架、钢挑架节点在中震、大震下进行有限元分析。计算和分析结果表明，所提出的各项性能目标都能得到实现，采用的性能化抗震设计和抗震措施都能满足结构的抗震设防要求。［关键词］特别不规则结构; 抗震性能设计; 节点设计中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2015)15-0051-05
Structural analysis and design on new comprehensive business building of a bankTang Yun(Ningbo Urban Construction Design and Research Institute Co., Ltd., Ningbo 315012, China)Abstract:The structure of new comprehensive business building of China Construction Bank Co., Ltd. Ningbo Branch, which adopts frame-shear wall structure system, is a special irregularity structure. Out-of-code design was introduced including response spectrum analysis under small earthquake, elastic time-history analysis and Pushover analysis. Appropriate performance objectives were proposed to key components and the corresponding seismic-resistance strengthening measures were adopted. Furthermore, the finite-element method was used in the design of key joint of steel truss and steel cantilever frame under moderate earthquake and rare earthquake. The results show that the structure can successfully achieve all the design goals and seismic-resistance performance design and seismic-resistance measures can meet requirements for seismic resistance.Keywords:special irregularity structure; seismic-resistance performance design; joint design
