[提要] 對啟東市長江新村12號(hào)砌體結(jié)構(gòu)住宅樓進(jìn)行了基礎(chǔ)隔震設(shè)計(jì)，采用時(shí)程分析法對隔震結(jié)構(gòu)的地震反應(yīng)進(jìn)行了計(jì)算。計(jì)算結(jié)果表明，隔震結(jié)構(gòu)在大震作用下仍處于彈性工作狀態(tài)，結(jié)構(gòu)由傳統(tǒng)抗震設(shè)計(jì)的“大震不倒”提高到“大震不壞”，具有優(yōu)越的抗震性能。
[關(guān)鍵詞] 砌體結(jié)構(gòu) 基礎(chǔ)隔震 時(shí)程分析Systemic isolation design of a brick masonry residence building in Qidong is processed. The aseismic behavior of the isolated building under earthquakes is studied with time history analysis method. The calculation results show that the isolated building keeps elastic state under seldonly occured earthquakes and has excellent aseismic behavior.
Keywords: brick masonry structure; base isolated; time history analysis
