Abstract: Extensive research is going on now a days on the structural performance with steel fibers along silica fume as an extension of the recent advances in concrete technology. This research presents a study in this direction to investigate the shear behavior as well as determining the cracking and ultimate shear capacities of with steel fibers and silica fume beams. In the this study consist three simply supports beams and an additional with steel fibers along silica fume. Measurements were recorded for the cracking load, the ultimate shear load, midspan deflection, maximum crack width, concrete strains at important locations and pattern of failure. The variables considered in this experimental program was the steel fibers Volumetric ratio Vf. It was establish that the rise of steel fibers (Vf) from (1-2%) improved the diagonal cracking load (Pcr) from 22-63% and growing ultimate shear load (Pu) from 51.21-180.46% correspondingly as associated to nonfibrous beams.
