［摘要］咸陽博物院屬于傳統(tǒng)風(fēng)格現(xiàn)代建筑，建筑群整體布局呈北斗七星狀布置，重點(diǎn)介紹項目三區(qū)秦文化展館的隔震設(shè)計。結(jié)構(gòu)采用基礎(chǔ)隔震框架結(jié)構(gòu)，每個框架柱下布置橡膠隔震支座。采用ETABS，SATWE軟件進(jìn)行隔震計算分析，同時驗算隔震支座在罕遇地震作用下的受力性能。計算結(jié)果表明，結(jié)構(gòu)采用橡膠隔震支座后，上部結(jié)構(gòu)樓層剪力明顯減小，地震反應(yīng)大幅降低。同時通過水平隔震縫及支座更換裝置的設(shè)計和布置，可釋放結(jié)構(gòu)變形和利于震后修復(fù)。

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
