is the compressive strength. ft is the tensile strength. and Vexp are the maximum load and shear capacity obtained from the experiment, respectively. VSFRC is the shear contribution of SFRC panels (VSFRC = Vexp−Vexp of the control beam). The shear enhancement ratio is calculated from Vexp/Vexp of the control beam. and VFEM are the maximum load and shear capacity obtained from FE analysis, respectively.
