Abstract

Abstract

An experimental study on shear performances of fiber-reinforced self-compacting concrete T-beam was carried out. Eight simple-supported T-beams subjected to two concentrated loading placed symmetrically were tested, to study the influences of fiber types, fiber contents and diameters, spacings and strength of stirrups on ultimate shear capacity, shear-force-displacement curves, longitudinal rebar strain and failure modes. The experimental results showed that the ultimate shear capacity of T-beams increased due steel fibers of being mixed or hybrid fibers. Fibers could restricted strain propagation of longitudinal rebars, delay appearance and development of cracks and change failure modes from brittle shear collapse into ductile flexural failure. The stirrups could be partially replaced by steel fibers or hybrid fibers. The design requirements for contents or strength of stirrups for beams could were reduced in combination with fibers and stirrups.
