摘要
设计了一种由滑动型和普通型橡胶支座组合而成的楼面隔震装置，通过振动台试验验证，滑移时的摩擦系数约为０．０１—０．０３，装置的隔震力学行为可以用双线性模型来模拟，只要第二刚度设计得当，这种装置的隔震效果可达５０％～８０％。
A floor isolator made up of sliding laminated bearing and rubber bearing is put forward and designed in this paper. A bi-linear model can be used to simulate its mechanical behavior. The friction coeffcient of sliding is about 0.01-0.03. The effectiveness of the system on decreasing re- sponse of acceleration using the present isolator, which can reach 50% to 80%, was confirmed by theoretical study and shaking table test.
