中文摘要：
通过实测数据处理及结构有限元模拟分析,给出了广东科学中心隔震支座健康监测一级、二级预警指标。基于隔震支座界限特性,建立了其压缩状态下的水平界限位移变形公式,并结合罕遇地震作用下隔震元件的水平位移变形控制,提出了三级、四级预警指标,为工程预警系统设置提供有效参数。
英文摘要：
Through the measured data processing and the finite element analysis of the structure,the primary and secondary level early-warning indices are given for the health monitoring of isolation bearings in Guangdong Science Center.Based on the boundary characteristics of isolation bearings,a formula for the horizontal boundary displacement of the isolation bearing under vertical compression is deduced.Referring to the control value of the isolation bearing deformation under the rare earthquake,the third and Fourth level early-warning parameters are set up,which may provide effective parameters for the early-warning system setting.
