The strength and deformation capacity of FRP members when subjected to shear forces are still largely unknown. This study reproduced the results of three-point bending tests by the finite element method. The shear behavior of GFRP members and its evaluation method were analytically investigated by changing the thickness and width of members in the analytical model including failure damage model. The analytical result found that the strength ratio decreased linearly as the web width-to-thickness ratio increased, and the strength ratio decreased exponentially as the flange width-to-thickness ratio increased.
