| 摘 要： | 根据屋盖结构的特点,提出柱顶隔震技术;随之,建立串联弹簧模型理论用于初步确定隔震垫参数,再使用非线性动力时程分析法进行详细设计。算例表明,屋盖隔震技术不仅大大降低了屋盖本身的反应,也有效保护了柱和基础等下部结构,而且屋盖侧移和隔震垫变形正常,因此柱顶隔震技术应用于屋盖结构是可行的。

| Abstract: | Roof-isolation is put based on the characteristics of the roof structure.Then the model of series spring is used to estimate the isolator parameters and the method of nonlinear dynamic history analysis is used for detail design.The results of the presented example indicate that the roof-isolation not only decreases the responses of steel roof,but also protects the columns and the foundation from earthquake,moreover the displacement of roof and the deformation of lead rubber bearings are in normal range,so roof-isolation can be used in roof structure. |
