Question: Rectangular drop beam is subjected to ultimate moment = ( Mu ) . This beam is to be reinforced by Elastic Glass Fiber Reinforced polymer

Rectangular drop beam is subjected to ultimate moment =(Mu). This beam is to be reinforced by Elastic Glass Fiber Reinforced polymer GFRP bars of tensile strength=1200 MPa, Elastic modulus =240 GPa, ultimate strain=0.005. Calculate the required percentage of GFRP bars that is needed such that concrete reaches ultimate strain at the same time of reaching GFRP strain =0.0035
