【摘要】 结构健康监测已成为现代建筑结构运营中的重要组成部分,而预警指标的设置又是结构健康监测系统中最为关键的一步,它能对结构在服役过程中的健康状态、损伤程度进行报警。本文通过广东科学中心E区隔震支座健康监测,并基于结构隔震层在罕遇地震下隔震支座的变形控制和隔震支座本身的界限特性与屈曲特性两种情况,设置了隔震支座的预警指标,并证实其可行性。更多还原

【Abstract】 Structural health monitoring is an important part for the operation of modern building and early-warming index setting is a key step of it,it can make a warming in the building service process according to the structure health state and damage degree.Based on the monitoring of isolation bearing in Guangdong science center area E.the early-warning indexes have been set up according to the deformation control of isolation bearing in isolation layer under severe earthquake and the isolation bearing’s property of extreme and buckling behavior.This index is confirmed feasibly.更多还原
