| 摘 要： | 在苏通大桥的塔、梁连接处分剐设置弹性连接装置和阻尼器.并选择恰当的弹性连接装置的弹性刚度以及阻尼器参数,利用Maxwell阻尼模型模拟黏滞阻尼器的滞回耗能特性,通过结构非线性地震分析的方法,对比了弹性连接装置与黏滞阻尼器的减震效果,分析表明弹性连接装置和阻尼器均能有效地减小梁端的地震位移,但阻尼器的效果更为理想.

| Abstract: | The elastic restraint and viscous dampers are applied to deck-tower connection of Sutong bridge and proper elastic stiffness constant of elastic restraint and viscous damper parameters are chosen.The Maxwell model is used for describing the hysteretic behavior of viscous damper.The nonlinear seismic analysis method is utilized for investigating the effects of elastic restraint and viscous damper to reduce the seismic response and the viscous damper is more ideal. |
