摘　　要：在罕遇地震荷载作用下,对椭圆抛物面网壳进行了时程分析,比较了结构在无控和有控状态下的结构响应,重点讨论了不同支座类型的最大支座反力,研究结果表明:该隔震方法对大跨度网壳结构的减震是可行的。Time-history method is used in the single layer elliptical parabolic latticed shell under the action for frequent rare earthquake. Comparing structure response between uncontrolled and controlled structure, it emphasie on the maximum reactions of supports with different support styles. The results have indated that can be demonstrated that isolation is effective for reducing the vibration of larxge span shell.
