摘要
基础隔震工程由钢筋混凝土结构、隔震支座组成。在地震作用下,主要由隔震支座变形吸收地震能量,以减少地震能量向上部结构的传递,使上部结构始终保持弹性工作状态;但钢筋混凝土结构的施工质量将直接影响到隔震支座的性能及耐久性。从大面积隔震结构工程隔震支座在非地震作用下产生水平位移原因、隔震工程钢筋混凝土结构施工中存在问题进行研究分析,制定解决方案,并成功在昆明规划馆项目中应用。
The base isolation project is composed of reinforced concrete structure and isolation bearing.Under the earthquake action,the seismic energy is absorbed by the deformation of the isolation bearing,so as to reduce the transmission of seismic energy to the upper structure and keep the upper structure in elastic working state all the time;however,the construction quality of reinforced concrete structure will directly affect the performance and durability of the isolation bearing.This paper studies and analyzes the causes of horizontal displacement of isolation bearing in large area isolation structure engineering under non earthquake action and the problems existing in the construction of reinforced concrete structure of seismic isolation engineering,and formulates solutions,which are successfully applied in Kunming Planning Museum project.
