In recent decades, reinforced concrete (RC) shear walls have been one of the best structural solutions to resist lateral load in high-rise buildings. Shear wall openings are essential for preparations and architectural requirements, which weaken the

Shear failure of RC beams is often sudden and catastrophic. The shear cracks progress rapidly without warning, and the diagonal cracks are considerably wider than the flexural cracks. In this study, two types of shear reinforcement are used, traditio
