Experimental and Numerical Retrofitting of Reinforced Concrete Bridge Piers

The use of a variety of bridge improvement and reinforcement methods has made significant progress in recent decades. Before strengthening, a study of the bridge should be done on how and in what way the useful life of the bridge can be extended. In this study, the seismic behavior of reinforced reinforced concrete columns was evaluated and compared with the distance of metal jacket and concrete jacket with dimensions of 3.5 x 3.5 m with reinforcement network. Models for estimating its seismic parameters were analyzed non-linearly geometric and materials. Use of concrete jacket box with dimensions of 3.5 x 3.5, increase energy absorption, final strength and ductility by 38, 14, 13 percent. Therefore, it can be concluded that by using a concrete jacket, the amount of items mentioned in the concrete column system can be increased.
