 This study examined the behavior of concrete slabs strengthened with either slurry-infiltrated matte concrete, Simkin, laminates or steel plates under both static and dynamic loading conditions. The results showed that Simkin's strengthening provided better performance than steel plates, particularly in terms of punching shear strength. Additionally, the FE model developed in this study accurately captured the behavior of the tested slabs, which suggests that it could be used to predict the behavior of similar structures.
