Reinforced concrete deep beams have wide range of applications and are used in gigantic structures to bear heavy loads. An opening in the deep beam decreases the load carrying capacity and reduces its serviceability. A PCC (plain cement concrete) deep beam with dimension 8000*5000*800mm (L*D*B) is modelled and analysed in ANSYS under uniform loading and simply supported conditions. The position of the circular hole with single and double opening is varied longitudinally and over the depth of the beam. The same beam is then analysed in ANSYS before and after assigning the CFRP (carbon fibre reinforced plastics) laminates along the inner surface of the opening. Stress in horizontal direction is studied in element below the CFRP laminate keeping loading condition, element type, and material properties constant. Thus the strength of the deep beam is a function of CFRP laminates as well as position of circular hole.
