国家会展中心(天津)B区3#塔楼结构设计

Strutural design of Tower 3 in zone B of National Convention and Exhibition Center(Tianjin)

国家会展中心(天津)B区3#塔楼,采用框架-核心筒结构,为B级高度的超限高层建筑。介绍了结构体系和性能目标的选取,对结构进行了小震弹性及时程分析、中震分析、大震弹塑性时程分析。计算结果表明,结构体系合理,可以实现预定的性能目标,具有较好的抗震性能。

The frame-tube structure of Zone B 3#tower of National Convention and Exhibition Center(Tianjin)is a super tall building with a height of B level.This paper introduces the selection of structural system and performance target,and conducts the elastic analysis and time history analysis of small earthquake,medium earthquake analysis and elasto-plastic time history analysis of large earthquakes.The calculation results show that the structure system is reasonable and can realize the predetermined performance target and has better seismic performance.
