Steel I-beams combined to concrete slabs make up composite beams, which are frequently used in construction worldwide. For ducts and pipes to pass through, the steel web of the composite beam is frequently perforated, saving space underneath the beam and maintaining clear spaces in buildings. The composite beam's load-bearing capacity and flexural performance, however, can be compromised as a result. Only a little amount of research has been done on the flexural behaviour of composite beams having reinforced web holes. The purpose of this study was to determine the effect of the kind and cross-sectional area of stiffeners on the flexural performance of full-scale composite beams with reinforced web apertures. A similar composite beam was created without the web opening for comparison's sake, and a composite beam with the web opening was built without reinforcement. The web holes strengthened with longitudinal stiffeners significantly increased the ultimate bearing capacity of the composite beams, as shown by the experimental results. The ultimate bearing capacity of the composite beam with reinforced web opening was comparable to that of the regular composite beam lacking web opening once the cross-sectional area of the double-sided longitudinal stiffeners reached the weakened area of the steel web opening. The final bearing capacity of the composite beam was not appreciably increased by the web holes strengthened with transverse stiffeners. The ultimate bearing capacity of the composite beams with reinforced web holes was also predicted using analytical methods by ABAQUS software
