摘要: 招商銀行總部大廈是一棟 387m 高的超高層建筑,采用框架-偏心筒-環(huán)帶桁架-伸臂桁架結構體系,核心筒偏置于建筑北側,設 5 個伸臂桁架加強層. 采用合理設計核心筒剪力墻厚度、增設環(huán)帶桁架等措施,減小了核心筒偏置對結構的不利影響. 在伸臂桁架中通過設置屈曲約束支撐(BRB),提高了整體結構的抗震性能. 利用屋頂水箱設置調(diào)諧液體阻尼器(TLD),減輕了結構風振效應. 大跨樓蓋跨中增設鋼次梁,減小了樓蓋人致振動加速度.同時展開了結構整體穩(wěn)定性、墻體受拉應力控制、長期荷載下的水平位移控制等多項研究,確保了該核心筒偏置的超高層結構的安全,所采取的設計方法和措施可供同類工程參考.

Abstract:China Merchants Bank Headquarters Building is a super high-rise building with the height of 387m, and adoptsframe-off-centre core tube-belt truss-outrigger truss structure systems. The off-centre core tube is located in the north of thebuilding, and five outrigger trusses reinforcement layers are set. Measures such as reasonable design of shear wall thicknessof core tube and adding ring truss were adopted, which reduces the negative impacts of the off-centre core tube on thestructure. The seismic performance of the overall structure is improved by utilizing the buckling restrained braces (BRBs)in the outrigger trusses. The roof tuned liquid damper (TLD) is set in the roof water tank to reduce the wind vibration effectof the structure. In order to reduce the floor vertical acceleration induced by human, horizonal steel beams in the middle ofthe long-span floor have been added. Meanwhile, a number of studies were carried out on the structural overall stability,the control of the tensile stress in the shear walls and the horizontal displacements under the long-term loads, etc. , toensure the safety of the super high-rise structure with off-centre core tube. The design methods and measures adopted canbe referred to the similar projects.
