［摘要］位于高烈度地區(qū)的澄江化石地博物館采用橡膠隔震支座隔震與屈曲約束支撐（BRB)消能減震聯(lián)合設(shè)計(jì)，該結(jié)構(gòu)采用了89個(gè)橡膠隔震支座、54個(gè)屈曲約束支撐。重點(diǎn)介紹了隔震支座選型與布置、支座位移和拉應(yīng)力分析以及BRB在不同工況下的耗能等內(nèi)容。結(jié)果表明，上部結(jié)構(gòu)地震響應(yīng)明顯降低，結(jié)構(gòu)抗震性能得到很大提高，通過對該工程實(shí)例進(jìn)行減隔震結(jié)構(gòu)設(shè)計(jì)分析，為今后減震與隔震聯(lián)合設(shè)計(jì)結(jié)構(gòu)在高烈度區(qū)的應(yīng)用提供參考。

Abstract: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 of 89 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.
Keywords:Chengjiang Fossil Museum; seismic isolation and energy-dissipation; high seismic fortification intensity site; isolation bearing
