- Synopsis:
- In this study, dynamic response analysis of a PC bridge was carried out by changing the gap size and type of rubber shock absorber. Damage of the end of bridge girder and the bridge pier bottom on the results of dynamic response analysis was evaluated by using the damage evaluation level introduced by the results of impact analysis of three-dimensional finite elements and the results of quasi-static cyclic loading experiments on actual scale RC bridge piers. As a result, it is clarified that rubber shock absorber of poly rubber fiber is effective on the pounfing of bridge girder.
