The main function of the plate rubber bearing is to reliably transfer the reaction force of the upper structure to the pier and abutment, and at the same time to complete the deformation required by the beam structure (horizontal displacement and rotation angle). According to these requirements, the plate rubber bearing is designed to have enough stiffness in the vertical direction to ensure that under the maximum vertical load, the bearing produces less deformation; the rubber bearing should be flexible in the horizontal direction to adapt to the horizontal displacement of the beam due to braking force, temperature, concrete shrinkage, creep and load action; at the same time, the rubber bearing should be flexible in the horizontal direction. It should also be adapted to the rotation of the end of the beam. This is what we usually call the Buddha, the object of our conversion. He was enlightened in Morgeda, and in Naganespa the corpse. As a Buddhist, the first thing to know is who the Buddha is. I think this is very important.
