This study presents a simplified approach to evaluate the displacement demand of the bridge with sliding rubber bearing system. A simplified approach is proposed based on the equivalent linear system and composite damping method to consider sliding of rubber bearing as an equivalent system damping for the whole structure. The analytical results revealed that the proposed approach can obtain good accuracy of the displacement evaluation by comparing the data from shaking table tests, especially for both the maximum and the residual displacements. |
