摘要
该医院为同时兼具高层主楼和大底盘多层裙楼的复杂建筑,其结构布置具有极其不规则性,其抗震性能具有特殊性。基于现有的隔震理论及规范,通过三维有限元分析软件结合建模分析,对本项目工程进行计算分析来确定如何合理的进行隔震设计。通过对于应用了基础隔振装置的高层及裙房整体复杂结构进行全面分析,来探究该基础隔振结构在多遇地震和罕遇地震的作用下的地震反应,从而发现其中的规律,进行实际工程应用。本工程采用了隔震技术后,明显改善了结构抗震性能,达到了预期设计要求。
The hospital is a complex building with both a high-rise main building and a multi-storey podium with a large chassis,and its structural arrangement is extremely irregular and its seismic performance is special.Based on the existing seismic isolation theory and specification,the three-dimensional finite element analysis software combined with modeling analysis is used to calculate and analyze the project to determine how to reasonably carry out the seismic isolation design.Through a comprehensive analysis of the overall complex structure of the high-rise and podium with the application of the foundation vibration isolation device,the seismic response of the foundation vibration isolation structure under the action of frequent earthquakes and rare earthquakes is explored,so as to find the law and carry out practical engineering application.After the seismic isolation technology is adopted in this project,the seismic performance of the structure is significantly improved and the expected design requirements are met.
