结合广东科学中心E区巨型钢框架结构的整个施工进程,对隔震支座的施工变形进行了监测,并对监测数据进行处理与分析,得出了焊缝收缩变形是隔震支座产生变形的主要原因,而支座的后期竖向变形则随着结构自重的增加得到有效的控制并有所减小。在此基础上,利用有限元分析软件定性地分析了杆件的焊接收缩变形对隔震支座的水平变形影响。同时,为保证结构的正常使用,对结构正常运营状态下的隔震支座实施了长达两年的监测,通过对采集数据的处理与分析得出隔震支座服役变形与环境温度作用线性相关。
Combined with the whole construction process of the giant steel frame structure in E zone of Guangdong Science Center, the construction deformation of the isolation bearing was monitored, and the monitoring data were processed and analyzed. It was concluded that the deformation of the welding joint was caused by the deformation of the isolation bearing Of the main reasons, while the late bearing vertical deformation with the increase of the weight of the structure is effectively controlled and reduced. On this basis, the finite element analysis software is used to qualitatively analyze the influence of welding shrinkage deformation on the horizontal deformation of the isolation bearings. At the same time, in order to ensure the normal use of the structure, the monitoring of the isolated bearing under the normal operating condition of the structure has been carried out for two years. Through the processing and analysis of the collected data, the linear deformation of the isolated bearing and the effect of the ambient temperature Related.
