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.

Elastic connection devices and dampers are set up at the tower and beam connections of Sutong Bridge. The elastic stiffness and damper parameters of the appropriate elastic connection device were selected, the hysteresis energy dissipation characteristics of the viscous damper were simulated by Maxwell damping model, and the shock absorption effect of the elastic connection device and the viscous damper was compared by the method of structural nonlinear seismic analysis, and the analysis showed that the elastic connection device and damper could effectively reduce the seismic displacement of the beam end, but the effect of the damper was more ideal.
