摘要
结合高烈度区工程实例,采用两阶段设计方法,设计并分析隔震结构各部位不同抗震性能要求及隔震构造,同时进行了隔震结构的抗震性能与隔震效果分析。研究结果表明:隔震结构满足高烈度区地震作用下的抗震需求,减震效果良好,同时又优化了建筑功能。在高烈度区,隔震是提高建筑抗震性能的一种性价比较高的方法。
Combined with the engineering example in high intensity zone,two stage design method was adopted to design and analyze different seismic performance of various parts of isolation structure and isolation construction,to provide a reference for isolation design.Seismic performance and seismic isolation effect of isolated structure were analyzed also.The analysis results show that the isolation structure could meet the seismic requirements in high seismic intensity area and has good damping effect,and the building function is optimized.So isolation is a method which has higher cost-effective to improve the seismic performance of the structure.
