Numerous researches have focused on the
contribution of steel fibers to the shear and flexural behavior of reinforced
concrete (RC) beams without web reinforcement. While it has been shown that the
addition of steel fibers makes concrete tougher and more ductile, there exists
a relatively limited amount of studies concerning the shear behavior of
polypropylene fiber reinforced concrete (PFRC) beams. For this purpose, an
experimental program was carried out for investigating the shear behavior of
PFRC beams. This paper presents the test results of PFRC beams with and without
web reinforcement. It is shown that the use of polypropylene fibers improved the
shear capacities of RC beams. However, the additional shear
resistance provided by polypropylene fibers was not sufficient to overcome the
shear demand and change the failure mode from shear to flexure.
