In this research, direct shear specimens, which have various volume fractions of fibers, concrete compressive strength and prestress level, were fabricated and tested to evaluate a shear behavior of SFR-PSC at crack interfaces. The shear strength of specimens increased as the prestress or the volume fraction of steel fibers increased. Particularly, the deformation capacity of SFR-PSC members significantly increased in cases of the volume fraction of steel fibers over 1.0 %.
