We have been studing the application of high strength continuous fibers as reinforcing materials for concrete. The aims are increasing the strength, improving the dulability and improving the electromagnetic characteristics of concrete structures. We have conducted flexural tests of partially prestressed concrete beams using braided Aramid fiber rods as main reinforcement and as prestressing tendons in pretensioning. In this paper, we disscussed load-deflection relatiouship compatibility of strains between concrete and the fiber rods and flexural crack characteristics of these PRC beams. And we also proposed the approximate solution of ultimate bending moment of concrete beams reinforced by such high strength fiber rods. From the result, bond properties of rods to concrete upto the large strain level was proved to be important.
