Abstract:
Previous relevant literature has confirmed that the inclusion of fibre reinforcement within a non-prestressed plain or conventionally reinforced concrete member enhances most of its strength and deformation characteristics. Properties such as concrete flexural and shear strengths, ductility, energy absorption and crack control are all improved. However, in this research an attempt is made to investigate the merits of using steel fibre reinforcement with prestressed concrete beams failing in shear. A study was carried out on the effect of high tensile strength crimped steel fibres on the shear strength characteristics of conventional prestressed concrete I-beams subjected to combined bending and shear, and failing in web-shear or flexure-shear.
