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。
Xianyang Museum belongs to the traditional style of modern architecture, the overall layout of the buildings was Big Dipper-shaped arrangement, focusing on the project Qin Wenhua three exhibition hall isolation design. The structure adopts the base isolation frame structure, and the rubber isolation bearings are arranged under each frame column. ETABS and SATWE software are used to calculate and analyze the isolated seismic isolation, and at the same time to check the bearing performance of the isolated bearing under rare earthquakes. The calculation results show that the shear stress of the superstructure floor decreases obviously and the seismic response decreases greatly when the structure adopts rubber bearing. At the same time, through the design and arrangement of the horizontal isolation seams and the bearing replacement device, the deformation of the structure can be released and the post-earthquake repair can be facilitated.
