This study studied the effect of using fiber on the shear strength of concrete beams without transverse reinforcement.The concrete mixture does not use coarse aggregate and uses stainless steel fiber with a diameter of 0.2 mm and a length of 36 mm.This study explains the effect of concrete quality on shear strength that can be carried by concrete beams with a ratio of 45 / 10.5,25 / 10.5 and 20 /10.5.The making of test specimens in this study was a beam of varying lengths of 110 cm,70 cm and 60 cm while a width of 7 cm,and a height of 12.5 cm.From the test results,the shear stress value is calculated using the formula v /(b x d x √(f c))> 2 in international units,in which the shear capacity value is bigger than the code states.Diagonal tension failure occurs on 110cm beam and shear tension failure on 70 cm and 60 cm beams.
