| Abstract: |
In order to improve the repair efficiency of bridge piers subjected to vehicle and ship collisions, an innovative replaceable pier structure based on flange connection and PBL shear connector was proposed. The finite element model of the replaceable pier and the traditional pier were developed and then validated through experimental test results. The behavior of replaceable pier and connection joint under lateral impact loading was studied based on numerical simulations. Compared with the traditional pier, it shows that the ability of new replaceable pier to resist impact loading is more favorable, and the connection component of new replaceable pier is repeatable. |
