基础隔震结构在天津市某软弱场地应用研究

Application Research of Base Isolated Structures in Tianjin at a Soft Site

基础隔震结构在坚硬场地土条件下应用广泛,其减震消能效果已经过工程实践验证,但却很少在软弱场地条件下应用。以在建的天津医科大学总医院滨海医院隔震结构为背景,对隔震支座在施工期间产生的变形进行现场监测和有限元模拟,总结了隔震支座在软弱场地产生变形的规律和特点,分析了产生变形的原因,并对施工过程提出了建议。

Base isolated structures is widely used in stiff site condition and its performance has been verified through practice. However,it is rarely used in soft site condition. The base isolated structures of Binhai Hospital of Tianjin Medical University is set in the background,during the construction period,the deformation of isolation bearing is tested and the finite element simulation is carried out,the features of the isolation deformation at soft site condition are analyzed and the reasons for the deformation are also examined. Suggestions for the construction are provided to reduce the isolation deformation.
