The research includes an analytical study using the finite element method for the reinforced concrete beams containing holes in the body. These tested trophies have a rectangular cross-section and without additional armament in the area of the hole,
and two patterns (patterned and simple support) were studied. As for the holes, they are rectangular in shape with variable dimensions, where prizes with one hole and prizes with two holes were chosen.
