Influence of X-Shaped Elastic-Plastic Steel Stop Block on Bridge Based on FEM

To ascertain the influence of the X-shaped elastic-plastic steel stop block on the lateral seismic response of the bridge, the research has been done to analyze the effect of the yield strength of the steel stop block and the height of the pier based on a simple supported beam bridge by the method of FEM. The result shows that in comparison with cases without steel stop block, the X-shaped elastic-plastic steel stop block is effective in reducing the relative displacement between the pier and the beam. The seismic response of the pier after setting the steel stop block is much influenced by the yield strength of the steel stop block and the height of the pier.
