In modem building nowadays requires many duct and pipe to provide audcomfortable accommodation. The dead space created between the beams and ceiling forudinstalling the ducts and pipe, this cause the overall floor height. Web opening inudconcrete beam is the only solution to provide a clear place to install with no decrease theudfloor clear height. There are a number of studies have conduct related to reinforcedudconcrete beam with web opening. This study aims to determine the deflection ofudreinforced concrete beam with 3 small opening by using finite element softwareANSYS.udThe beam model is simply supported beam with two concentrated andudsymmetricaludloads. There are six elements of the beam been manipulated to formuddifferentudmodal. There are modulus of elasticity, reinforcing steel bar size at the bottomudandudsurrounding the opening and concrete cover, apply loads, and shear link spacing.udTheudeffect of the apply loads is very significant and follow by concrete cover. However,udothersudelement is insignificant of affecting the beam deflection. Based on this study, the udeffect of reinforcing steel bar size, shear link spacing and-concreteud.udstrength is veryudinsignificantudand might be ignored, if the reinforced concrete beam with opening areudwelluddesigned.
