“…Hence, study of web opening is needed to be done in order to produce steel section with least material but results in highest efficiency without compromising the safety factor consideration. However, based on the static and dynamic analysis, the higher values of stresses are observed near the opening (El-Dehemy, 2017). Besides that, the best location of web opening is middle two-third of the span (Morkhade and Gupta, 2019).…”

Purpose Due to the enormous increase in economic development, structural steel material gives an advantage for the construction of stadiums, factories, bridges and cities building design. The purpose of this study is to investigate the behaviour of bending, buckling and torsion for I-beam steel section with and without web opening using non-linear finite element analysis. Design/methodology/approach The control model was simulated via LUSAS software with the four main parameters which included opening size, layout, shape and orientation. The analysis used a constant beam span which is 3.5 m while the edge distance from the centre of the opening to the edge of the beam is kept constant at 250 mm at each end. Findings The analysis results show that the optimum opening size obtained is 0.65 D while optimum layout of opening is Layout 1 with nine web openings. Under bending behaviour, steel section with octagon shapes of web opening shows the highest yield load, yield moment and thus highest structural efficiency as compared to other shapes of openings. Besides, square shape of web opening has the highest structural efficiency under buckling behaviour. The lower buckling load and buckling moment contribute to the higher structural efficiency. Originality/value Further, the square web opening with counter clockwise has the highest structural efficiency under torsion behaviour.

“…However, the corners of rectangular openings are prone to high-stress concentrations, making them more critical than circular openings. The impact load response of steel structures and their relationship with the initial shape has only been examined in a few studies [9,11,48]. Based on their research, the reasons for failure differed significantly depending on the shape of the openings.…”

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.

“…It was found that the shape of the web opening has a minor effect on the natural frequency. El-Dehemy [13] analyzed the stress and deflection patterns of steel beams with web openings (SBWOs). The results showed that the deflection value of the steel beam increased as the number of openings increased.…”

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.
