新疆高端人才创新创业大厦结构设计

Structural design of Xinjiang High-end Talent Innovation and Entrepreneurship Building

新疆高端人才创新创业大厦由2栋高度分别为93.6m和72.6m的塔楼组成,塔楼之间设置连桥,连桥跨度26m,大于超限高层设计要点中连桥跨度24m的要求,需进行全国超限专家审查。进行了8度设防区连体结构的抗震性能化设计,结果表明,结构满足小震弹性、中震下核心筒抗剪弹性和抗弯不屈服、大震下核心筒截面抗剪不屈服的抗震性能目标。对连桥采取了小震、中震及大震分析,进行包络设计,所得出的应力比满足要求。重点分析了连体层对塔楼楼层的影响,分析结果表明,B塔楼对A塔楼沿连桥方向有侧向支撑作用。

Xinjiang High-end Talent Innovation and Entrepreneurship Building is composed of two tower buildings with height of 93.6m and 72.6m respectively. There is a 26m-span connection bridge between two towers, which exceeds the requirement of 24m-span connection bridge in out-of-code design key points. So a national expert review is needed. The performance-based seismic design on the connected structure in the 8 degree seismic precautionary zone was conducted. The results show that the structure meets seismic performance objectives of the shear elasticity and not yielding of eorewall under frequent and fortification earthquakes, and not yielding of eorewall section under shear forces under rare earthquake. Analyses were conducted on the connection bridge under the frequent, fortification and rare earthquakes respectively, and envelope designs were conducted to obtain the stress ratio that meets the requirements. Effect of the connection layer on tower floors was emphatically analyzed and the analysis results show that the Btower has lateral support function on Atower along the connection direction.
