［摘要］以阿圖什市人民醫(yī)院門(mén)診醫(yī)技樓為工程實(shí)例，詳細(xì)介紹了消能減震結(jié)構(gòu)設(shè)計(jì)的過(guò)程。首先闡述了消能減震的必要性并根據(jù)初步計(jì)算設(shè)定了預(yù)期的減震目標(biāo)，其次利用ETABS軟件對(duì)非減震及減震結(jié)構(gòu)進(jìn)行了多遇地震下的時(shí)程分析，最后利用PERFORM-3D軟件對(duì)減震結(jié)構(gòu)進(jìn)行罕遇地震下動(dòng)力彈塑性分析，對(duì)結(jié)構(gòu)的整體性能及關(guān)鍵構(gòu)件的性能進(jìn)行了評(píng)估，并闡述了關(guān)鍵構(gòu)件的設(shè)計(jì)方法，同時(shí)通過(guò)對(duì)減震結(jié)構(gòu)及非減震結(jié)構(gòu)的對(duì)比分析，論證了設(shè)置阻尼器在罕遇地震下可以使結(jié)構(gòu)有更大的彈塑性變形和強(qiáng)度儲(chǔ)備，可以滿足“大震不倒”目標(biāo)。

Abstract:The Outpatient Medical Technology Complex of Artux People′s Hospital was taken as an example to introduce the design process of energy dissipation structural design. Firstly, the necessity of energy dissipation  was expounded and energy dissipation target was set according to preliminary calculations. Then time-history analysis was conducted on the non-damping and damping structures under frequent earthquake using ETABS software. Finally dynamic elasto-plastic analysis was conducted on the structure under rare earthquake using PERFORM-3D software. The performance of the overall structure and the key components of the structure were assessed, and the design method of key components was expounded. Through analysis and comparison of non-damping and damping structures, it demonstrates that the structure can have greater elastic-plastic deformation and strength reserve under rare earthquake by setting dampers, and the structure can meet the target of “not collapsing under rare earthquake”.

Keywords:high seismic intensity zone; energy dissipation; damper; rare earthquake; dynamic elasto-plastic
