A novel elastic-plastic sphere bearing with given fusing capacity is proposed in this paper, which can simultaneously control the pier damage and the relative displacement between girder and pier. To investigate the performance of the novel bearing developed in this paper, the compression-shear tests are carried out. It shows that the robustness of shear capacity of the fusing system is validated by the experimental test results，the expected goals of displacement and energy-dissipation of steel- ring damper elements are also achieved. To further illustrate the efficacy of proposed bearing in simultaneously controlling pier damage and displacement of girder, the demonstration case using a continuous girder bridge model is presented. It shows that the seismic behavior of bridges can be controlled by using the novel elastic-plastic sphere bearing developed in the paper. |
