ABSTRACT
The service life of structural buildings may encounter dynamic loads such as impact and explosion loads, which can occur accidentally, such as vehicle collisions or explosions. As a result, studying the structural behaviour of members in dynamic scenarios is essential. In addition, the incorporation of web openings in these members is an important aspect of structural engineering. However, It leads to a complicated of factors that greatly influence the overall performance and behaviour of the structure. The purpose of this article is to review the studies on the primary factors affecting the dynamic behaviour of the cellular steel beams under impact loading. This will be accomplished by discussing experimental, numerical and analytical studies. Also, the utilized guidelines in designing buildings to resist impact loads were reviewed. The study found that incorporating a slab greatly enhances the load-bearing and shear strength of a composite beam when subjected to impact, surpassing that of a steel beam without a slab. The size and positioning of web holes greatly affect the behaviour of perforated steel beams, especially the stress distribution in these beams.
Keywords: Cellular beams, elongated web openings, impact load, composite beam, slab thickness.
