Abstract:Four prestressed concrete T-beams were constructed with aramid-based prestressing and parallel fiber rods. Three beams included an externally applied fabric shear reinforcement. The beams were tested and the performance of beams with external fabric shear reinforcement were compared to a control beam without external shear reinforcement. The tests indicate that fiber rods serve as effective prestressing tendon with excellent bond characteristics and shear response predicted by ACI equations. The tests also indicate that the externally applied woven fabric can provide the shear resistance. External shear reinforcement using nonmetallic fabric offers significant opportunities for strengthening existing structures as well as for fabrication of nonmetallic structures.
