［摘要］北京CBD文化設(shè)施采用鋼框架-支撐結(jié)構(gòu)體系，設(shè)計難點主要為大跨度、大懸挑及樓板開大洞等。采用ABAQUS軟件進行建模，并利用ABAQUS軟件的瞬態(tài)動力學分析技術(shù)對此結(jié)構(gòu)進行了彈性時程分析與彈塑性時程分析，分析了結(jié)構(gòu)在多遇地震與罕遇地震作用下的時程響應。計算結(jié)果表明，結(jié)構(gòu)的各項指標均滿足規(guī)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
