［摘要］阿圖什市人民醫(yī)院分院病房樓為采用了基礎(chǔ)隔震技術(shù)的框架\|剪力墻結(jié)構(gòu)體系。主要介紹工程的設(shè)計(jì)過程：首先設(shè)計(jì)隔震層；其次在中震作用下采用ETABS軟件進(jìn)行動力時程分析，得出隔震后水平向減震系數(shù)，并在SATWE軟件中將上部結(jié)構(gòu)根據(jù)隔震分析結(jié)果按降低一度進(jìn)行設(shè)計(jì)；最后還采用PERFORM-3D軟件進(jìn)行了隔震結(jié)構(gòu)體系的動力彈塑性分析。結(jié)果表明，在大震作用下，整體結(jié)構(gòu)和各類結(jié)構(gòu)構(gòu)件均滿足抗震性能設(shè)計(jì)目標(biāo)要求。

Abstract:The ward building of the Branch of Artux People′s Hospital adopts frame shear wall structural system with base isolation technology. The design process of the project was mainly introduced. First isolation layer was designed. Based on the ETABS software, the dynamic time-history analysis was conducted under fortification earthquake to obtain the horizontal damping coefficient after seismic isolation. According to the results of isolation analysis, the upper structure was redesigned after reducing one degree of earthquake intensity, and dynamic elastic-plastic analysis was carried out on seismic isolation structural system by PERFORM-3D. The results show that the whole structure and all kinds of members under rare earthquake can meet the requirements of seismic performance design objectives.
Keywords:complicated high-rise building; performance-based seismic design; elastic time-history analysis; seismic isolation design
