Özet

In this study, the effects of different blending and combination of macro and micro steel fibers on the shear strength, ductility, failure mode and crack propagation of hybrid fiber reinforced self-compacting concrete beams were investigated experimentally and statistically. In the design of concrete, straight steel micro and hooked steel macro fibers were used. For this purpose, twelve 200x200x1000 mm reinforced concrete beam specimens, which had same reinforcing bar details, were produced and tested under four-point bending to investigate ultimate shear strength, displacement ductility, crack patterns, mode of failure, energy absorption capacity and yield stiffness properties. In conclusion, the beam specimens produced from self-compacting concrete (SCC) with hybrid steel fiber prevented the shear failure while all SCC beam specimens containing hybrid steel fiber reached the ultimate bearing capacity with the mode of flexural failure. Also, it can be clearly emphasized that the SCC beam specimens with hybrid steel fiber had higher shear strength, energy absorption capacity and yield stiffness than those of beam specimens containing only macro or micro steel fiber.
