dc.description.abstractPunching shear resistance is crucial in structural design, particularly for flat slab systems. Numerous studies have demonstrated that the use of steel fibers or synthetic fibers in concrete structures is an effective method to enhance punching shear strength. Each fiber type has different mechanisms of action and varying degrees of influence on the structure's load-bearing capacity. The authors evaluate experimental data from 273 fiber-reinforced slabs and 84 control slabs to assess the impact of fibers on improving the strength and durability of flat slabs. The research indicates that integrating multiple fiber types enhances the mechanical performance of concrete in flat slab systems, underscoring the necessity for optimizing fiber combinations. However, knowledge gaps remain regarding the influence of fiber properties on punching shear resistance, which constrains the optimization of design parameters. Further investigation is required to refine predictive models and evaluate fiber combinations to improve structural performance in high-durability, safety-critical applications.
