Abstract
<p>This paper presents an experimental and analytical study on the behavior of a bridge superstructure with double spherical sliding bearings subjected to live load. Two single span superstructure models with an I-section beam supported by two spherical sliding bearings were tested under static loadings to investigate the influence of live loads to the double spherical sliding bearings, and the experiments were simulated by 2D finite element analyses. It is found that a slider of the bearing tends to be returned to the stable positon without residual displacement after the cycle of loadings. Also, the finite element analyses show that there could be a stress concentration to the slider due to the rotation and displacement of the bearing.</p>
