SHEAR STRENGTH OF PRESTRESSED CONCRETE BEAMS WITH FRP TENDON

Abstract

The shear resisting model for concrete beams reinforced with FRP rod which was proposed by the authors is expanded to predict the shear strength of prestressed concrete beams with FRP tendon. The shear resisting model consists of four shear resisting forces which are defined as functions of prestressing force, concrete strength, shear span to effective depth ratio, stiffness of tendon and shear reinforcement. The applicability of the model is confirmed by comparing with experimental results.
