刚泰国际中心1号楼结构设计

Structural design of building NO.1 of Gangtai International Center

刚泰国际中心1号楼为总高度298.7m的超限高层,采用型钢混凝土框架+核心筒+伸臂桁架结构体系。介绍了1号楼结构体系的特点,采用SATWE和MIDAS两种软件对结构进行反应谱分析、弹性时程分析并对结果进行分析比较,对结构关键部位及构件进行验算分析,并采用ABAQUS对结构进行了罕遇地震作用下动力弹塑性时程分析,保证抗震设防目标及多道防线的实现。

Building NO.1 of Gangtai International Center is a super high-rise building with the total height of 298.7 meters.The structural system which is composed of steel reinforced concrete frame,core tube and outriggers.The structural system characteristic,the main results of CQC analysis and elastic dynamic time-procedure analysis were introduced systemically based on the program of SATWE and MIDAS.The key parts and components of the structure were checked and analyzed,and the dynamic elastic-plastic analysis of the structure under major earthquakes was analyzed by ABAQUS.On the base of the above,then to fulfill the seismic performance objectives and seismic fortification requirements.
