A series of nine under-reinforced concrete T-beams were tested to study the effectiveness of using externally applied composite fabrics as a method of increasing a beam's flexural capacity. Woven composite fabrics made of glass fiber, and glass fibers were bonded to the web and bottom of the T-beam using a epoxy bond. The three different fabrics were chosen to allow various fabric stiffness and strengths to be studied. The beams were tested in flexures, and the performance of six beams with stirrups was compared to results of three control beams without stirrups. Three beams failed in compression and the rest in shear. The beams with composite fabrics displayed excellent flexural capacity. For the enhanced strength by U-Jacket and bottom composite fabrics., increases in ultimate strength of 30 to 100 percent were achieved.
