On the basis of Chinese and foreign specifications and the latest research findings, an appropriate parameter determination method for bridge reinforcement with prestressed carbon-fiber-reinforced polymer (CFRP) plates was proposed to determine the key design indices and calculation coefficients. Each item of prestress loss was studied and a novel calculation method was proposed to determine the usage amount and effective stress of prestressed CFRP plates for reinforcement design, in consideration of the relevant construction technology and anchorage system. The feasibility and reliability of the suggested method in this paper were verified by using an RC simply supported beam bridge reinforcement project as an example.
