隔震结构设计方法研究

Research on design method for base isolation structure

随着隔震技术在高烈度区越来越多的应用,对隔震结构的合理设计方法及流程化的重要逐渐凸显。结合云南某酒店工程中隔震结构设计的一般流程,即前期方案比选阶段、上部结构设计阶段和隔震系统设计阶段,阐述了隔震结构的设计方法。前期方案比选阶段主要是隔震技术的可行性、经济性、适用性分析,上部结构设计阶段需要注意地震力的取值、合理的模型建立、隔震支座上一层的刚度等,隔震系统设计阶段主要包括隔震支座的选型与布置、上、下支墩尺寸的设计。

With the application of base isolation being used more and more frequently,the importance of reasonable design method and process standardization is obvious.According to a real project in Kunming,the basic design method and checkpoints in the whole design process were introduced.This design process includes analysis of feasibility and economy at the beginning period of the project,the designing of the upper structure in which the reasonable seismic force and calculated model should be paid attention and the base isolation system designing,including figuration of isolation units,buttress designing.
