| 摘 要： | 铅芯橡胶支座有较高的初始刚度,又能允许较大的变形,可以提高桥梁抗震性能。通过模拟铅芯橡胶支座的滞回性能,把支座和桥梁当作一个整体考虑,进行非线性时程计算。分析了铅芯支座的抗震效果,比较了铅芯支座在不同的桥面刚度和不同基础刚度下的抗震效果。

| Abstract: | Lead-Rubber Bearings have a higher original stiffness and can be easily distorted,that will help to promote the anti- earthquake function of bridges.This paper analyses the effectiveness of seismic reduction of the bridge equipped with lead-rubber bearings,simulates the quality of its delayed circle- curve,makes an non-linear time-history response calculation,and finally compares the the surface stiffness and the foundational stiffness of bridges. |

| Keywords: | bridge Lead-Rubber Bearings delayed circle- curve time-history response analysis. |
