铅芯橡胶减震技术在渡槽中的应用研究

Seismic response reduction for aqueduct by using LRB

本文探讨了铅芯橡胶支座用于渡槽减震的有效性， 对一实例通过非线性时程分析法研究了在不同地震波激励下的地震作用效应， 表明采用铅芯橡胶支座较普通的叠层橡胶支座具有更多优点， 可实现对地震响应多目标控制．

In this paper,the effect of LRB on reduction of seismic response of aqueduct is discussed.The response of aqueduct under different ground motion is investigated by using nonlinear time\|history response analysis procedure.It shows that LRB has much more advantages than RB and possesses the effect of multilateral seismic reduction.
