［摘要］北京CBD文化设施采用钢框架-支撑结构体系，设计难点主要为大跨度、大悬挑及楼板开大洞等。采用ABAQUS软件进行建模，并利用ABAQUS软件的瞬态动力学分析技术对此结构进行了弹性时程分析与弹塑性时程分析，分析了结构在多遇地震与罕遇地震作用下的时程响应。计算结果表明，结构的各项指标均满足规范要求。

Abstract:Beijing CBD Cultural Center adopts braced-steel-frame structural system. Difficulty in design mainly results from large-spans, large-cantilever spans and large-openings in the floor system. The transient dynamic analysis technique of ABAQUS software was used to develop a 3-dimensional finite element  model for undertaking elastic time-history analyses under frequent earthquakes and elasto-plastic time-history analyses under rare earthquakes. Calculation results show that  all structural indexes can meet code requirements.

Keywords:Beijing CBD Cultural Center; ABAQUS software; elastic time-history analysis; elastic-plastic time-history analysis
