Abstract:An experiment building of research and development in Beijing is a high-rise building. The optimization process of buckling-restrained brace fit in frame-shear wall structure system and the out-of-code structural characteristics were briefly introduced. The whole structure was calculated and analyzed by  PKPM software, and stress analysis of super long floor under temperature effects was carried out by  MIDAS Gen software, and the  3D3S software was used to carry out the calculation and analysis of the large-span steel truss and composite slabs with profiled steel sheet. The analysis results show that all the indicators of the whole structure meet the demands of codes, and the seismic performance of the structure is well and the structure is safe and reliable, which can provide reference for the similar structure type of  projects.

Keywords:high-rise building; buckling-restrained brace; frame-shear wall; slab stress analysis; steel truss; design indicator; seismic performance
