Utilization of Sustainable and Smart Materials in Slender Shear Walls- a Deep Insight

Abstract:

Tall buildings require slender shear walls as fundamental structural elements since the structure’s performance and safety depend on the walls' capacity to bear lateral loads while retaining their ductility. Concrete that has short fibers, like those made of steel or glass is known as fiber concrete. By increasing the ductility of concrete, these fibers can increase its resistance to brittle shear failure. This work aimed to investigate the effects of fiber concrete on thin shear wall ductility. The ductility of fiber concrete shear walls is significantly higher than that of typical concrete shear walls, according to tests conducted on thin shear walls made of both types of concrete. This occurred because of the fibers in the fiber concrete filling up the cracks and stopping them from getting worse. It has been stated that fiber concrete can be utilized as a building material in a variety of ways after being treated. Its application to cylinder shear walls has not been documented solely, though. Therefore, a thorough assessment of the literature regarding the potential of steel fiber concrete for the prevention of shear cracks. The optimal choice for fiber concrete in this application is characterized by a high fiber aspect ratio and a minimum fiber volume fraction of 1%, with steel fiber concrete being highly recommended. The study's findings imply that slender shear walls' ductility can be increased and their resistance to brittle shear failure increased by using steel fiber concrete.
