［摘要］阿图什市人民医院分院病房楼为采用了基础隔震技术的框架\|剪力墙结构体系。主要介绍工程的设计过程：首先设计隔震层；其次在中震作用下采用ETABS软件进行动力时程分析，得出隔震后水平向减震系数，并在SATWE软件中将上部结构根据隔震分析结果按降低一度进行设计；最后还采用PERFORM-3D软件进行了隔震结构体系的动力弹塑性分析。结果表明，在大震作用下，整体结构和各类结构构件均满足抗震性能设计目标要求。

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
