An efficient method for the construction of bridge piers

In this paper, a new method for the construction of bridge piers using prec ast prestressed concrete (PPC) panels as formwork is proposed in order to i ncrease the efficiency of construction. Scaled down experiments were perfor med to check the feasibility of the proposed method. Experiments were carri ed out on six different reinforced concrete column specimens. These experim ents were performed to check whether the PPC panels acted as an integral pa rt of the structure due to good bonding between panels and core concrete. L oad-displacement behavior, crack pattern and other experimental data were a nalyzed and the experimental results compared with numerical simulations to check the effectiveness of the construction method. It was interesting to observe that the use of panels did not create any weakness in the structura l behavior of the specimen and can be used effectively for the construction of bridge piers.
