【 摘 要 】

The reinforced concrete main building structure of a 600 MW thermal power plant is taken as the background project. The buckling restrained brace (BRB) is used as the energy dissipation element to optimize the seismic design of the original frame bent-brace structure. Through time history analysis of the original structure and three kinds of shock absorption structures, their seismic performance under rare earthquakes is compared. The results show that the BRB can effectively control the displacement response at the weak layer, improve the internal force distribution of the structure, and make the structure meet the requirements of 8 degree fortification. In the high intensity area, the reinforced concrete frame bent-BRB (RCFB-BRB) structure is worth popularizing.
