Abstract

A number of fiber reinforced plastic (FRP) rods can be used as fully bonded tendons in pretensioned prestressed concrete (PC) members. In this research project, the development and flexural bond lengths of braided epoxy-impregnated FRP tendons made of aramid fiber were examined. Development length was determined by performing a three-point flexural test (static monotonic load), and flexural bond length was computed on the basis of previous knowledge of transfer length. Variables included tendon material/manufacturing (flexible FRP rod, rigid sand-adhered FRP rod, and seven-wire steel strand), tendon size and number, initial prestress force, and presence or absence of shear reinforcement. It is found that development length of braided aramid FRP tendons is relatively short. Recommended values of development length expressed in terms of nominal tendon diameters are given.
