天元港国际中心结构设计

Structural Design of Tianyuangang International Centre

天元港国际中心是一座多功能商业写字楼。工程主体结构基础采用了CFG复合地基加平板式筏基基础,工程沉降满足规范限制。上部结构为框架-核心筒结构体系,采用了现浇预应力空心楼板,并通过设置暗梁等其它措施,使预应力空心楼盖的受剪、受弯、抗裂等都满足要求。工程整体计算分析结果表明,结构的层间位移角满足规范要求,说明结构设计合理。总结了结构设计中采取的若干技术措施,可供类似工程参考。

Tianyuangang International Centre is a multi-function commercial lettering building. The CFG composite ground and fiat raft basement are adopted in the foundation design. The frame core-tube system is used in the upper structure, and the prestressed hollow floor slab is applied. The hidden beams and other measures are adopted, and the bearing capacities of moment, shear force and anti-crack meet the requirement. The results of structural analysis show that the inter-story displacement angle is rational, which indicates that the structural design is reasonable. The measures in the design are concluded, and the structural design can be referred in similar engineering.
