橡胶支座被广泛应用于公路、铁路桥梁中,其作用是将上部结构的力可靠地传递给墩台,并同时完成梁体结构所需的变形,从而有利于延长建筑物的使用寿命。在垂直和水平方向上,支座应具有足够的刚度和柔度,从而保证在最大荷载作用下支座产生较小的变形及适应梁体由于荷载制动力、混凝土的徐变、荷载作用等引起的水平位移,同时能适应梁曲扰需要而能灵活转动,其主要特点是弹性好、减震强、变形小。根据以上特点,橡胶支座同时作为一种有效的结构减震装置,也被
Rubber bearings are widely used in highways and railway bridges. Their function is to transmit the force of the superstructure to the piers and abutments, and at the same time to complete the deformation required for the structure of the beam so as to prolong the service life of the building. In the vertical and horizontal direction, the support should have sufficient rigidity and flexibility to ensure that the support under the maximum load to produce smaller deformation and adapt to the beam body due to load braking force, concrete creep, load caused by Of the horizontal displacement, and can adapt to the needs of the beam and can flexural rotation flexibility, its main feature is good elasticity, strong shock absorption, small deformation. According to the above characteristics, rubber bearings at the same time as an effective damping device structure is also
