摘　　要：在隔震方案设计中,由于地震动的高度随机性和隔震体系对地震频谱的敏感性,单纯依靠GB 50011—2010《建筑抗震设计规范》中规定的依据特定的地震波来评定隔震结构的水平减震系数,缺乏一定的可靠性。除利用GB 50011—2010方法进行隔震层的设计外,补充在大量地震动作用下的基于概率统计分析得出的隔震前后结构的层间剪力减震系数,用于增强隔震体系减震系数的可靠性,并对某工业厂房进行详细的隔震分析。Due to the randomness of ground motion and the sensitivity of the seismic spectral, it lacks certain reliability merely relying on Code for Seismic Design of Buildings （GB 50011--2010 ） on the basis of three groups, or a set of three or seven waves to assess the level of structure damping coefficient. In the paper, in addition to the methods of GB 50011--2010 for vibration isolation layer design, the damping coefficient for inter-storey shear force before and after isolation was calculated by probability and statistics analysis. It was used to increase the reliability of the vibration isolation system damping coefficient, and the vibration isolation performance of a industrial plant was analyzed in this way.
