介绍一种新型隔震层的构造和工作原理,通过对多种工况下的隔震层试件进行振动台试验,研究隔震层在不同隔震层高度和不同加速度幅值输入时的动力特性,研究隔震层在不同隔震层高度和不同加速度幅值输入时的隔震层相对位移及加速度的减震效果。试验结果表明,该隔震层减震效果明显。当隔震层高度增加或加速度输入幅值加大时,隔震层的减震系数提高。当输入加速度到达一定幅度时,相对位移增加幅度下降,说明该隔震层具有可靠的位移限制能力。
The construction and working principle of a new kind of isolation layer are introduced. Through the shaking table test of the isolation layer under a variety of working conditions, the dynamic of the isolation layer at the input of different isolation height and different acceleration amplitudes Characteristics, study the seismic isolation layer in different height and different acceleration amplitude input isolation layer relative displacement and acceleration damping effect. The test results show that the seismic isolation effect is obvious. The damping coefficient of the isolation layer increases when the height of the isolation layer increases or the amplitude of the acceleration input increases. When the input acceleration reaches a certain magnitude, the relative increase of displacement decreases, indicating that the seismic isolation layer has a reliable ability to limit the displacement.
