Because of having light weight, high strength, good durability and other characteristics, prestressed CFRP reinforcement technology has become a new kind of reinforcement technology. Base on the test, the mechanical properties of prestressed CFRP concrete beams are analyzed. The calculation formula for normal section flexural capacity of the pre-stressed CFRP concrete beams is put forward. The test results are generally slightly higher than the results got by the cal-culation formula, which shows that the theory calculation values are conservative and have the security of reserves.
