Strengthening Solutions for Deep Reinforced Concrete Beam with Cutout Opening

Since reinforced concrete (RC) buildings have long service life, cutout openings are generally needed in their load-bearing walls as a sustainable solution order to meet new requirements of users. However, the decrease capacity walls, which may result failure buildings. In this paper, we investigate possibility making door opening RC wall an existing building Gävle Sweden. The studied current paper rests on two individual supports at its ends; thus, it is considered deep beam. called examined (EW) here. StruSoft FEM-Design software used study model, analyze, and design based Eurocodes Swedish national annex. potential need for EW be strengthened when made also evaluated. It concluded that strengthening with needed. Different solutions proposed EW. Moreover, situation assessed regard utilization ratio, deflection, weight. Consequently, demonstrated function well
