On the basis of relevant test, the curved bear capacity of carbon fiber cloth reinforce reinforcing bar steel fiber concrete beam is studied.

This paper makes experimental study of stress character of reinforced concrete beam's oblique section in negative area strengthened with U-jackets carbon fiber reinforced polymer (CFRP).

The static load test was done on the frame beam strengthened by CFRP with frame joint anchored in different mode, and the bearing capacity, deflection and width of crack was surveyed.
