Abstract: The architectural from of Shanghai Zhangjiang Science Hall is complex, and it has many structural characteristics such as seismic irregularity, super long steel structure, center of mass deviation and large-span truss transfer. The main structure adopts the steel frame-buckling restrained brace structural system, and it also adopts the viscous damper damping system and the mixed energy dissipation technology which combines the velocity damper and displacement damper to give full play to the advantages of two different types of dampers. The selection of structural system and the consideration of structural layout were mainly introduced, as well as the analysis of key technical problems in structural design including the analysis of torsional displacement ratio considering the influence of dampers, the analysis of mixed energy dissipation and the construction simulation analysis of large-span truss transfer.
Keywords:steel frame-buckling restrained brace structure； large-span truss transfer； construction simulation； viscous damper； velocity damper； buckling restrained brace；displacement damper； mixed energy dissipation technology
