摘要
针对滑动摩擦支座的特点建立了可以考虑支座竖向动反力对摩擦力影响的双向滑动支座模型。应用所建立的支座模型,通过算例对竖向动反力对支座滑动性能的影响进行了探讨,结果表明,竖向动反力对于桥梁结构地震反应有较大的影响。
According to the characteristics of the sliding bearing, a bi - directional sliding bearing model is set up, which can consider the influence of the bearing dynamic vertical resistance force on the bearing frictional force. By using the model, the effects of vertical dynamic resistance on the performance of sliding bearing are deeply explored through an example. The result shows that the vertical dynamic resistance influences the seismic reaction of bridge structures greatly and should be paid more attention to in analysis.
