中文摘要：

通过高层隔震和非隔震结构的模型振动台对比试验，研究高层隔震结构的地震反应特性、隔震效果以及减震机制。结果表明：高层隔震结构的楼层加速度、层间住移反应比非隔震结构明显降低，隔震效果明显；在高宽比为4的情况下，试验隔震支座未进入受拉状态；高阶振型对非隔震结构的影响程度远大于隔震结构的情况，隔震降低了结构基本振型反应的同时有效抑制了高层结构高阶振型的反应，这成为长周期高层隔震结构仍然能够取得较好隔震效果的主要原因。

英文摘要：

The comparison tests of shaking table in the high-rise isolated and non-isolated structure models were conducted to investigate the seismic behavior, isolation effect, and isolation mechanism of a high-rise isolated structure. The results showed that the present isolation system was reduced, with the maximum ac- celeration and inter-storey drift for all floors of the isolated structure model compared with that of the non- isolated structure. In the situation of aspect ratio 4 of the test model, the test isolators did not reach tension state. It was found that the effects of higher modes in the non-isolated high-rise structure were more signif- icant than that on the isolated one, and the present of isolation layer reduced the seismic responses of the fundamental mode and the high-order mode of high-rise structures, thus having the good isolation effects of the high-rise isolated structure.
