Commercially available current FRP stirrups with circular section suffer from premature failure at bent-portion by stress concentrations and kink of fibers during the fabrication process. In this research, CFRP stirrups with rectangular section (CFRPRS) has been developed, which can alleviate the aforementioned problems existing in the conventional FRP stirrups with circular section. The experimental comparisons were made between the beams with CFRPRS stirrups and conventional stirrups to observe the effectiveness of CFRPRS in resisting shear.
