Creating an opening in the reinforced concrete beam is sometimes required, the transverse openings through beams are a source of potential weakness. This paper study the retrofitting of this beam especially in the case of fire exposure. Retrofitting the opening in the shear zone using either internally discrete steel fibers in concrete mix or externally ferrocement layer around the opening location. An experimental program of Reinforced concrete beams with 150 mm circular opening diameter design to investigate the effect of Internal and External retrofitting to beams behavior with and without exposure to a direct fire of 500oC for one hour. The experimental results verified by theoretical calculation for beam shear resistance according to ACI specifications. Adding discrete steel fiber increase the residual stiffness of the test specimens after firing, decrease the rate of the deflection gain during firing, the retrofitting with Ferrocement has decreased this reduction, deflection, change in crack pattern shape and improved beam ductility. Ferrocement layer is equivalent to 1% of Steel fibers in improve failure load otherwise, the Steel fibers more affected the deflection more than ferrocement layer.
