［摘要］咸阳博物院属于传统风格现代建筑，建筑群整体布局呈北斗七星状布置，重点介绍项目三区秦文化展馆的隔震设计。结构采用基础隔震框架结构，每个框架柱下布置橡胶隔震支座。采用ETABS，SATWE软件进行隔震计算分析，同时验算隔震支座在罕遇地震作用下的受力性能。计算结果表明，结构采用橡胶隔震支座后，上部结构楼层剪力明显减小，地震反应大幅降低。同时通过水平隔震缝及支座更换装置的设计和布置，可释放结构变形和利于震后修复。

Abstract: Xianyang Museum belongs to the traditional style modern architecture, the whole layout of the building group is arranged in the shape of “Big Dipper”, and the isolation design of the Qin Dynasty Culture Pavilion in the third district of the museum was mainly introduced. The structure adopts the frame structure with  foundation isolation, and  rubber isolation bearing was arranged under each frame column. ETABS and SATWE software were used for isolation analysis and calculation of mechanical performance of isolation bearings under the rare earthquake. The calculation results show that after the application of the rubber isolation bearing in the structure, the floor shear of upper structure  and seismic response reduce significantly. At the same time, the design and arrangement of the horizontal vibration isolation joint and the bearing replacement device can release the structure deformation and is conductive to post-earthquake rehabilitation.

Keywords:traditional style architecture; foundation isolation; isolation bearing
