| الوصف: | In the recent past the use of steel fibers to improve the mechanical properties of concrete has been the prime research area in structural applications. The paper makes an attempt to study the improvement of shear strength of high strength concrete beams (65 MPa) with different shear span to depth ratios (a/d = 1, 2, 3, and 4) and various dosages of fibers (0.4%, 0.8%, and 1.2% by volume of concrete) only in shear predominant regions, without shear reinforcement. The experimental studies were validated analytically by modeling the beams in ANSYS. The investigations revealed an increase in shear capacity with addition of fiber at different shear span to depth ratios (a/d) ratios. Further the test results of the beams with fiber only in critical regions indicated almost the shear capacity similar to that of the beams reinforced with fiber throughout, thus usage of fiber in shear critical regions shall be more cost effective. |
