河北国际商务广场C#写字楼的结构抗震性能及层间剪力比分析

Structural seismic performance and interstory shear strength analysis of Hebei International Business Square C# Office Building

河北国际商务广场C#写字楼采用混凝土框架-核心筒结构体系,结构高度152.9m,属B级高度超限高层建筑结构。通过弹性分析、弹性时程分析和动力弹塑性时程分析,对结构进行了抗震性能化设计;针对项目首、二层层高相差较大,层间剪力比较难满足规范设计要求的问题,对不同结构方案分别进行了弹性分析和采用有限元软件ABAQUS进行了大震动力弹塑性时程分析。

Hebei International Business Square C# Office Building adopts frame-corewall structural system. The structural height of the building is 152. 9m. It is belong to B grade high-rise building. According to elastic analysis,elastic timehistory analysis and dynamic elastic-plastic time-history analysis,the performance-based seismic design is studied. To address the problem that when the height of first floor and the second floor has larger difference,the layer shear force ratio was difficult to satisfy the demand of the code,elastic analysis and elastic-plastic time-history analysis by finite element software ABAQUS under the rare earthquake about the different structure scheme were carried out.
