摘要:
为充分了解板式橡胶支座对斜交连续梁桥地震反应的影响,利用OpenSees软件建立简化的斜交桥计算模型进行时程分析,研究板式橡胶支座摩擦滑移效应,以及支座动摩擦系数、剪切刚度、局部脱空等参数对斜交桥地震反应的影响。结果表明:板式橡胶支座考虑摩擦滑移后,不仅桥面位移和转角显著增大,而且出现残余位移和残余转角;随着支座剪切刚度的增大,桥面位移和转角均明显减小;随着桥墩处支座动摩擦系数的增大,桥面位移、转角均呈增长趋势,然而桥台处支座动摩擦系数的影响与之相反;桥墩处局部支座脱空对斜交桥的影响明显大于桥台支座。
Abstract:
In order to fully understand the influence of plate rubber bearing on the seismic response of skew continuous girder bridge, a simplified calculation model of skew bridge is established for time history analysis by OpenSees, the influence of laminated rubber bearing friction sliding, and the parameters such as dynamic friction coefficient, shear stiffness, local bearing separation on the seismic response of skew bridge is studied. The results show that the displacement and rotation angle of deck increase with friction sliding of the laminated rubber bearing, and the bridge deck appears residual displacement and residual rotation angle; the displacement and rotation angle of deck decrease with the increasing of bearing shear stiffness; the displacement and rotation angle of bridge deck both tend to increase with the increasing of dynamic friction coefficient of pier bearing, but the abutment bearing produces the opposite effects; and the effect of the local pier bearing separation on skew bridge is greater than abutment bearing.
