橡胶垫侧向刚度的实验测定

Determination for the Lateral Rigidity of Sandwich Rubber Bearings

夹层橡胶垫能消耗较大的地震能量,降低上部结构的地震反应。为了测试模型一阶频率、二阶频率,在隔震结构上布置四个力平衡传感器,推算橡胶垫的侧向刚度作为实际工程应用中的夹层橡胶垫的水平刚度。

The sandwich rubber bearings can reduce the energy of vibration and can minish the seismic response of the upside structure.In order to obtain the first and the second-order frequency,four force-balanced sensors are fixed on the isolated structure,the lateral rigidity of the sandwich rubber bearings are determined as the engineering application.
