［摘要］新疆喀什体育中心地处高烈度区，依据设定的结构抗震性能目标，需对看台结构进行消能减震设计，通过看台结构的各消能减震设计方案的对比分析，确定了看台结构采用框架-BRB结构形式。进行小震弹性和大震弹塑性时程分析，计算结果均能满足相关要求，且框架-BRB相比原结构基底剪力也有所减小，同时采用BRB延缓了主体结构产生塑性铰的时间，改善其受力状态，起到耗散地震能量和第一道抗震防线的作用。

Abstract:Kashi Sports Center in Xinjiang is located in high seismic intensity area, and on the basis of set structural seismic targets, energy-dissipated design should be conducted on the stand structure. Different energy-dissipated design schemes on the structure were compared and analyzed to determine the stand structure using the frame-BRB structural form. Elastic analysis under frequent earthquake and elastic-plastic time-history analysis under rare earthquake were conducted, and the calculation results met the relevant requirements. The base shear force of frame-BRB structure also decreased compared to that of the original structure, while the use of BRB could delay the emerging time of the plastic hinge in main structure to improve the stress condition and act as roles of seismic energy dissipation and the first seismic fortification line.

Keywords:energy dissipation structure; buckling restrained brace（BRB）; energy-dissipated design
