Abstract: One kind of CFRP bars produced in China is used to replace normal steel reinforcing bars in unbonded prestressed concrete beams and the corresponding anchorage devices are developed at the same time. Experimental studies on behaviors, prestressing loss, norma-l section bending capacity of the unbonded prestressed concrete beams reinforced with CFRP bars are carried out, and corresponding conclusions are got. -
