【提要】 天元港國際中心是一座多功能商業(yè)寫字樓。工程主體結(jié)構(gòu)基礎(chǔ)采用了CFG復(fù)合地基加平板式筏基基礎(chǔ)，工程沉降滿足規(guī)范限制。上部結(jié)構(gòu)為框架核心筒結(jié)構(gòu)體系，采用了現(xiàn)澆預(yù)應(yīng)力空心樓板，并通過設(shè)置暗梁等其它措施，使預(yù)應(yīng)力空心樓蓋的受剪、受彎、抗裂等都滿足要求。工程整體計(jì)算分析結(jié)果表明，結(jié)構(gòu)的層間位移角滿足規(guī)范要求，說明結(jié)構(gòu)設(shè)計(jì)合理?？偨Y(jié)了結(jié)構(gòu)設(shè)計(jì)中采取的若干技術(shù)措施，可供類似工程參考。

Structural Design of Tianyuangang International Centre/Zhang Huaiyong,Dai Weiming,Wang Shule(China Architecture Design & Research Group,Beijing 100044,China)Abstract:Tianyuangang International Centre is a multifunction commercial lettering building.The CFG composite ground and flat 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.
