Abstract: By using the self-developed CFRP-PCPs， the mounted reinforcement was conducted onRC beams． A correction formula of deflection was deduced base on current Chinese codes，the calculated value is in good agreement with the experimental value． The experimental results show that compared with the mounted reinforcement of concrete beams by prestressed CFRP tendons，the embedded reinforcement of concrete beams by CFRP-PCPs not only effectively improves the structure of the force performance and deformation capacity，but also solves the problems of complex construction process of post-tensioned anchoring device，high costs，etc．
