摘　　要： 结构性能的可预演与可控制是结构性能设计的核心内容,工程结构的复杂性以及结构性能影响因素的不确定性是目前实现结构性能设计和目标控制的难点。基础隔震结构因隔震层的设置使结构性能控制的对象相对集中、性能影响因子大大减少,并且隔震支座的性能可实验、可预演、可控制,构件易更换。本文以该思想为指引,将性能设计的理论应用于某隔震结构工程设计,通过对隔震层性能目标的控制来实现整体结构的性能设计和目标控制,对结构在多种地震作用工况下的位移和楼层加速度进行分析,对结构在多级性能设防条件下的性态目标进行分析和评价。结果表明:该隔震结构在多个地震作用工况下性能反应良好,性能控制目标明确,并可实现多级目标设防。因此,作者认为基础隔震结构是目前实现工程结构性能设计的很好途径和实践。 Controllability and preview are the core contents of performance based design of structure,while the complexity of structures and the uncertainty of the factors that affect the performance of structure are the difficulties of achieving structural performance design.The performance of bearing can be experimented,previewed and controlled,so the study factors that affect the performance of the base isolation structure are dramatically reduced,the control objects of structural performance are relatively concentrated.To study the response of displacement and acceleration of base isolated structure under multilevel seismic fortification criterion,performance based design is applied in a base isolated building in this paper.It's demonstrated by the analysis result that base isolated structure is a pretty approach to achieve performance based design and performance object control.
