作者对一个二层复合隔震结构钢框架模型进行了振动台试验,该模型采用夹层橡胶支座与摩擦滑移支座并联组合作为隔震层,既能提供足够的弹性恢复力,又具有良好的结构耗能能力.试验测得结构各项动力响应,并将软件计算数据与试验数据进行了比较,结果表明复合隔震结构的加速度反应小,楼层层间位移也较小,上部结构基本为平动,结构耗能能力显著,而且软件可以很好地模拟结构的地震反应规律.
作者對一箇二層複閤隔震結構鋼框架模型進行瞭振動檯試驗,該模型採用夾層橡膠支座與摩抆滑移支座併聯組閤作為隔震層,既能提供足夠的彈性恢複力,又具有良好的結構耗能能力.試驗測得結構各項動力響應,併將軟件計算數據與試驗數據進行瞭比較,結果錶明複閤隔震結構的加速度反應小,樓層層間位移也較小,上部結構基本為平動,結構耗能能力顯著,而且軟件可以很好地模擬結構的地震反應規律.

A two-floor steel-frame model of composite isolation structure is tested to simulate the earthquake action on shaking table. The isolator layer of model is combined by laminated rubber bearings and sliding isolation bearings. It can provide sufficient elastic resilience and consume earthquake energy effectually. Structure dynamic response in the test was compared with that of analysing in the software. It is shown that frame acceleration response and relative storey displacement are both small in composite isolation structure, which can consume large earthquake energy, then it can be reflected by the software analysing.
