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
