Abstract: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 corewall under frequent and fortification earthquakes,  and not yielding of corewall 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 B tower has lateral support function on A tower along the connection direction.

Keywords:Xinjiang High-end Talent Innovation and Entrepreneurship Building; super high\|rise structure; reinforced concrete frame-corewall; performance objective; connected structure
