Many times it can be needed to make an opening in the shallow beams, for example, works of air conditioning pipes and the transgression of electricity cables. But it was more complicated in deep concrete beams because the large size of the beam can accommodate the dimensions of the openings and different use may be a door for people to cross or ventilation window may be up to the corridor in the garage and so. Therefore, it should be paid attention to the openings in the deep concrete beams, not only for the large dimensions of the opening but also for the safety of the deep beam means the safety of the whole building because it usually carries more than floors. This, unlike shallow beam which carries loads from one roof. Hence, researchers began to conduct studies of deep beams with openings on both sides design as a new structure and strengthen the openings to increase durability. In this paper, we will study the effect of opening on a deep concrete beam and develop a practical solution to compensate for the shortage in the resistance of the beam. Eight beams were saluted by using the associated program, one of them was solid, one of them was with two opening and six beams with strengthening with steel jacket at the tie area. The results of this paper are that the selected opening reduced the resistance of the beam by an approximate 20% and we proposed a suggestion to make up for this shortfall of resistance to make it easier to create opening in deep concrete beams safely.
