摘要
桥梁支座是连接桥梁上、下部结构的重要构件,对桥梁墩台的受力状态、梁的水平位移、转角都起着十分重要作用,板式橡胶支座广泛应用于各种形式的桥梁。通过对常用的板式橡胶支座压剪性能的试验,分析支座静摩擦系数、动摩擦系数、剪切刚度与压应力和水平力的频率拟合函数表达式,对支座使用时的受力状态、破坏前临界力的分析计算具有一定的参考性。
Bearing is the primary component of a bridge which connects superstructure and substructure,which has a significant influence on the load state of pier and abutment,as well as beam horizontal displacement and rotation.The laminated rubber bearing is widely used in all types of bridge.In this paper,the static and dynamic friction coefficients,as well as fitting function of shear stiffness with compressive stress and horizontal force frequency of common laminated rubber bearing are analyzed through compression-shear testing.It can be referred in calculating the bearing load state under normal use and the critical force approaching failure.
