Abstract
This paper investigates the seismic performance of the repair and retrofitting damage unskewed multi-column RC bridge pier under in- plane lateral cyclic loading. The main objective of this paper is to determine the seismic performance of repaired bridge pier in terms of lateral strength capacity, stiffness, ductility, damage state, and equivalent viscous damping. Three layers of Carbon Fiber Reinforced Polymer (CFRP) are wrapped along the damaged specimen. This technique is used to repair and strengthen the bridge pier column after damage due to earthquake. The experimental results show that the repaired bridge pier performed very well under in-plane lateral cyclic loading. It also increases the lateral strength capacity, ductility, and equivalent viscous damping as compared to the specimen before retrofitting. This technique can be recommended for repair of damages of bridges after the earthquake or any other natural disaster.
