Abstract In building structure, The story height can be minimized by providing openings in beams which serves for the utility equiments passing through.The dead space in false ceiling in thus, put to economical use in the form of a substantial reduction in materials and construction cost.In the case of streel structure, There is no critical risk in the structural strength because of reinforcing methods of stiffness and steel palte but in the case of reinforced concrete strucrure, proper provision should be made in designing these openings, otherwise there is a risk that these opening will possibly weaken the structural strength of the building frame to a critical degree. In this paper, for the numerical analysis of the reinforced concrete beams with circular opening in the web, expecting stress concentration of the circular opening, reinforcing methods were studied.Twenty test pieces with each different reinforcing methods were tested and their resisting forces were defined.
