Paramatric Analysis of Stress Increment of Prestressed CFRP Reinforced Concrete Bridge Deck

By using the ANSYS model, this paper studied the fluence caused by tension control stress, ratio of reinforcement, ratio of CFRP bar and concrete strength on stress increment of concrete bridge deck unbonded partially prestressed with CFRP bars. A formula was fitted out about the relationship between the ultimate stress increment of CFRP tendons and comprehensive reinforcement parameter(β0).
