摘要: 前海时代广场是由两栋超高层建筑组成的大底盘双塔高位连体结构.针对建筑高宽比大、荷载作用大、复杂连体、功能复杂、限制条件多等特点,通过对不同结构方案进行对比,确定了大底盘双塔高位连体结构采用钢桁架强连接形式,北塔采用带立面支撑的矩形钢管混凝土框架-核心筒结构体系,南塔沿高度采用三种不同的结构体系.对所选结构体系采用 YJK 与 MIDAS Gen 软件进行弹性分析对比.分析和论证结果表明所选结构体系可行且合理.

Abstract: Qianhan Time Plaza is a twin-tower high-level connective structure with large chassis,which is composed of twosuper high-rise buildings. Taking into account of big height-width ratio,large loads,complex connective structure,complexfunctions,limited condition,etc. ,through the comparison of different structural schemes,it was determined that the steeltruss with strong fixed connection form was adopted by the twin-tower high-level connective structure with large chassiss.The north tower uses rectangular steel pipe concrete frame-RC core wall structural system with facade brace,the south toweradopts three different structural systems. YJK and MIDAS Gen programs were used for elastic analysis and comparison ofthe selected structural system. The analysis and demonstration results show that the choosing structural systems are feasibleand reasonable.
