摘要

由于地震响应特性对斜拉桥结构影响较大，在塔梁之间合理设置粘滞阻尼器可改善斜拉桥抗震性能。而目前研究多针对具体工程未考虑斜拉桥面相对高度对粘滞阻尼器减震效果影响。以某斜拉桥为模型，通过改变其下塔柱高度改变斜拉桥面相对高度，并系统分析桥面相对高度对斜拉桥粘滞阻尼器减震效果影响。研究表明，桥面相对高度对粘滞阻尼器最优参数及最优减震效果均有较大影响。

Abstract

The cable-stayed bridge’s structural system have great influence on seismic response characteristic. Studies show that proper elastic viscous damper between the tower and girder can improve the seismic behavior of cable-stayed bridge. However, conclusions at present are mostly drawn from some specific engineering without considering the influence of the different relative height of deck on viscous damper’s shock reduction effect on cable-stayed bridge. By changing the height of the lower tower as the relative height of deck, the author analysis the influence of relative height of deck on tower-girder viscous damper’s shock reduction effect on cable-stayed bridge using a certain cable-stayed bridge model. According to the study, the relative height of deck of cable-stayed bridge has an outstanding influence on the damper’s optimal parameters and the optimum shock reduction effect.
