Abstract
The characteristics of the seismic bearing change depending on various factors When an earthquake occurs the behavior of the bridge may differ from the values expected in the structural design The shear deformation of the seismic bearing may increase but it is difficult to reach the fracture deformation This paper studied the effect of the stiffness due to various dependency and durability on Lead Rubber Bearings LRB and the over strength of bridge piers on the bearing behavior when an earthquake occurred As a result if the stiffness of LRB reduces within the criteria seismic performance can be expected safety even if the shear strain designed in the current design is greater than the allowable shear strain The reason is that the hardening phenomenon in the high strain region of the laminated rubber bearing suppresses the displacement Also since the seismic bridges with over strength of the piers have come near elastic behavior when an earthquake occurs shear strain is easy to be large
