“…The study revealed that all studied steel beams experience similar deformation patterns and failure modes when subjected to various moments and shear forces. A numerical investigation carried out by [41] examined the vibration behaviour of steel beams featuring rectangular web openings. The natural frequency showed slight changes when different web opening arrangements were utilized.…”

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.

“…As an action to understand the behavior of such beams under high loading rate, different theoretical and practical studies were conducted last decade to show how such beams reacted to dynamic loads. Steel beams with rectangular web openings were the focus of a numerical analysis conducted by Srivastava et al [12]. It was found that the shape of the web opening has a minor effect on the natural frequency.…”

The absence of specific guidelines to enhance the integrity of structural members to resist accidental loading such as impact, explosion and fire highly motivated the researchers to cover such a knowledge gap. In the current study, one of the most common structural members that used widely in structural frames named steel beams with large web openings (SBLWOs) was numerically investigated under impact load. Non-linear finite element (FE) models were created using ABAQUS software and validated against existing experimental data from the literature. The FE models developed considered the dynamic material properties in the elastic, plastic, and damage stage. Strain rate effect was also taking into account in the models. Afterwards, intensive parametric analyses of the parameters that affect the behavior of SBLWOs were performed including impact energy, impact location, and opening strengthening. The correlation outcomes of the FE and the experimental tests were in a good agreement in terms of force and displacement time histories and failure modes. The results showed that the SBLWOs were able to resist the impact with higher velocity rather than higher mass. Regarding the effect of impact location, the worst case was found to be when a cellular steel beam impacted close to the supports. Finally, the contribution of providing steel stiffeners in the impact zone resulted in a significant improvement in the shear and web buckling resistance.
