Abstract:
The objective of this investigation was to determine the feasibility of replacing shear reinforcement stirrups with randomly distributed steel fibers for the prevention of diagonal tension shear failure in full-scale conventionally reinforced concrete beams. The following conclusions are based upon the use of steel fibers with deformed ends Dramix to replace stirrups 1 Steel fibers can be used to replace stirrups in beams with no reduction in the ultimate design moment capacity 2 Steel fibers increase the shear strength of concrete beams sufficiently to prevent catastrophic diagonal tension failure, while forcing the beam to fail in flexure 3 ACI Code procedures can be used without modification to design reinforced concrete beams that contain steel fibers as shear reinforcement 4 Low volume percentages of steel fibers have no effect upon the stiffness of full-scale beams and 5 Steel fibers present a potentially more economic alternative to the use of stirrups in reinforced concrete design.
