Abstract

Due to the experimental nature of the investigation, it is not possible to quantify the punching shear transfer mechanisms. In addition, these calculations do not account for the impact of fiber length, fiber shape, or fiber length-to-diameter ratio on the punching shear resistance of slabs. These factors have a major effect on the binding strength of steel fibers in concrete, which has an effect on the strength of the concrete, which affects the punching shear capacity of SFRC slabs. In the case of thin slabs with a large span-to-thickness ratio, flexural deformation dominates the slab's behavior. In this study, the modal features of small-scaled concrete slab models were explored using the commercial program ANSYS 16 and compared to earlier studies. The ANSYS results revealed that the geometry model used to perform a mode shape animation is animatable. This study examines the deformation differences between two types of SFRC and the influence of these changes on slabs. The final finding was that the addition of steel fibers considerably improves the punching and shear resistance of the slabs. Utilizing steel fibers with a fiber volume between 30 and 60 kg/m3 increases the punching shear resistance of the slabs in direct proportion to the fiber volume.
