Structural Design and Analysis of the 63 storey Main Tower of Guangdong International Building

本文通过广东国际大厦63层主塔楼的设计,对筒中筒结构在风力和地震、竖向荷载、竖向构件轴向变形、温度变化和楼板预应力张拉等影响下的位移和内力作了分析。还与用有机玻璃模型的试验结果作了对比。

This paper introduces the structural design of the 63 storey main tower of Guangdong International Building now under construction in Guangzhou city. It describes fully the displacements and internal forces of a tube-in-tube structure subjected to wind loads and earthquake actions as well as the effects caused by axial deformation of vertical members under vertical loading, the variation of temperature and the deformation of flat slabs under prestressing. The results of theoretical calculation have been compared with a model test.
