Restrained Concrete Shrinkage in Case of Strengthened Bridge Piers By Concrete Jacketing
Abstract eng: Reinforced concrete (RC) jacketing of weak bridge pier columns is an effective retrofitting technique, particularly in seismic regions. The effect of restrained concrete shrinkage on the strength of concrete jackets is investigated in this study. A series of compressive tests are performed on square prism concrete specimens where steel plates are placed to represent the restrained shrinkage effect on the concrete of the jacket. Then, a numerical procedure to simulate the concrete shrinkage effect using the finite element method is proposed and results are justified and validated using the experimental data. The results indicate that restrained concrete shrinkage considerably reduces the stiffness and the maximum load of the strengthened elements.
