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。
The struelure 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 intr^utuced including response spectrum analysis under small earthquake, elastic time-histnry analysis anti Pushover analysis. Appropriate perhu＇mance objectives were proposed to key components and the corresponding seismie-resistanee 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.
