［摘要］上海张江科学会堂建筑形体复杂，且具有多项抗震不规则项、超长钢结构、质心偏置、大跨度转换等结构特点。主体结构采用钢框架-屈曲约束支撑结构体系，并同时采用黏滞阻尼器减震系统，采用速度型阻尼器与位移型阻尼器相结合的混合减震技术，充分发挥了两种不同类型阻尼器的优点。文章重点介绍了结构体系选型考虑因素和结构布置，以及结构设计过程中的关键技术问题分析，包括考虑黏滞阻尼器影响的扭转位移比分析、混合耗能减震分析、大跨度施工模拟分析。

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
