位于高烈度地区的澄江化石地博物馆采用橡胶隔震支座隔震与屈曲约束支撑(BRB)消能减震联合设计,该结构采用了89个橡胶隔震支座、54个屈曲约束支撑。重点介绍了隔震支座选型与布置、支座位移和拉应力分析以及BRB在不同工况下的耗能等内容。结果表明,上部结构地震响应明显降低,结构抗震性能得到很大提高,通过对该工程实例进行减隔震结构设计分析,为今后减震与隔震联合设计结构在高烈度区的应用提供参考。
The Chengjiang Fossil Museum located in high intensity area adopts the joint design of rubber isolation bearing isolation and buckling restraining brace (BRB) energy dissipation and damping. The structure adopts 89 rubber isolation bearings and 54 buckling restraining supports. The selection and arrangement of isolation bearings, the displacement and tensile stress analysis of the bearings and the energy consumption of BRB under different operating conditions are introduced. The results show that the seismic response of the superstructure is obviously reduced and the seismic performance of the structure is greatly improved. Through the design and analysis of the seismic isolation structure in this project, the reference for the future application of the joint design of the seismic isolation and isolation in the high seismic intensity area is provided.
