Abstract:
Describes current applications of carbon, aramid, and glass fiber reinforced plastic (FRP) materials in prestressed concrete civil engineering structures in Japan and other parts of the world. Compared with conventional reinforcing bars and prestressing steels, FRP materials strengthened in one direction generally have a small modulus of elasticity and linear coefficient of expansion. However, these materials have high strength and excellent corrosion resistance. They are also lightweight and nonmagnetic. Several bridges are described in which FRP products have been used as prestressing tendons and external post-tensioning cables.
