以山西省太原市某中学改扩建项目为例,从楼层剪力比及水平地震影响系数计算,罕遇地震下支座分析、隔震橡胶支座水平位移限值验算等方面,对隔震结构进行了分析,并对隔震设计中的难点进行了探讨,从而提高建筑的抗震性能。 Taking the reconstruction and expansion project of a middle school in Taiyuan, Shanxi as an example, from the aspects of floor shear ratio and horizontal seismic influence coefficient, bearing analysis under rare earthquake and checking of the horizontal displacement limit of isolation rubber bearings, Analyzed, and discussed the difficulties in the design of isolation, so as to improve the seismic performance of the building.
