摘　　要：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 seismic isolation and energy-dissipation combined design was used in Chengjiang Fossil Museum with rubber isolation bearings and buckling restrained brace（BRB） in high seismic fortification intensity site,the structure consisted of89 rubber isolation bearings and 54 buckling restrained braces.Selection and arrangement of isolation bearings,the displacement and tensile stress analysis for isolation bearings,the energy dissipation of BRB in different cases were focused on.Analysis results show that the seismic response of upper structure could be significantly decreased and the seismic performance is improved significantly.Through the seismic isolation and energy-dissipation structural design and analysis of the engineering example,it provides a reference for the application of seismic isolation and reduction combined design of the structure in high seismic fortification intensity sites.
