Openings in concrete beams is preferred than using extended dropped ceilings to accommodate utility ducts and pipes. This leads to significant cost saving but unfortunately, beam strength and serviceability are affected. Experimental study of behavior of steel fiber concrete beams with different reinforcement methods around opening by using external glass fiber reinforced polymer (GFRP) or internal additional steel bars, the usage of steel fibers increases ultimate load (Pu) by 24% and deflection (∆u) by 69% with elastic plastic behavior and initial stiffness (I.S) increases by 17%, post cracking stiffness (P.I) decrease by 24% and energy absorption (E.A) increase by two times. On the other hand, GFRP is used in beam specimen that doesn’t contain steel fibers in the concrete mixture, Pu increases by 42% and ∆u increases by 88%
