Go to Editorial ManagerThe behaviour of slabs under impact loading differs significantly from that observed under short-term or long-term static loading conditions. Such dynamic loading scenarios typically arise from vehicular collisions, explosive events, or other forms of sudden impact. This paper aims to synthesise and critically evaluate the extant literature concerning the response of slabs subjected to impact loading. The investigation encompasses an analysis of the salient factors influencing slab behaviour, elucidation of failure mechanisms, examination of methodologies for simulating impact loading, and a critical appraisal of pertinent design code recommendations. Through this comprehensive review, it has been ascertained that reinforcement configuration plays a pivotal role in augmenting the resistance of slabs to impact loading. Furthermore, the predominant mode of failure observed in such scenarios is punching shear. This finding underscores the necessity for meticulous consideration of shear capacity in the design of impact-resistant slab structures.
This research reviews existing literature on RC beams strengthened techniques for shear. Research indicates that fiber-reinforced polymers (FRP) are best utilized and effective materials to enhance RC beams. These materials have corrosion resistance and exceptional strength. The strengthening of reinforced beams by FRP depends on the nature of fiber, arrangement, materials, and manner of strengthening. The current article analyzes the properties, advantages, and applications the FRP composites. In addition to the mechanisms of failure, properties, and behaviors of FRP-strengthened reinforced beams undergoing shear with various strengthening techniques such as EB, NSM, and ETS.
