“…The inclusion of a concrete slab typically led to an increase in the bearing capacities of the specimens. Two steel beam-column joints, one with an RC slab and one without, underwent a series of trials to examine their impact behaviour [34]. Based on the data analysis, it was determined that the behaviour of connections is greatly influenced by both the type of connections and the properties of the slab.…”

“…Hence, over the past ten years, there have been attempts to examine the impact of load on steel beams. This effort aims to enhance our understanding of how these elements react under intense loading conditions [19,[32][33], [34][35]. Some researchers have explored the potential of solid and perforated steel beams [36][37] To mitigate the risk of progressive collapse caused by floor impact.…”

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.

“…To adequately analyze the structural safety of RC members under impact loading, both flexural capacity and maximum deflection response must be estimated (Fujikake et al, 2009). Numerous researchers and scholars have explored RC structures under severe loads (e.g., earthquakes, blasts, impact) (AL-Bukhaiti et al, 2021;Dok et al, 2021;Heng et al, 2021;Jia et al, 2021;Liu et al, 2020Liu et al, , 2021Tran et al, 2021;Wang et al, 2021;Yanhui et al, 2022;Zhao et al, 2021).…”

With the fast growth of high-speed rail in recent years, derailment has become the first hidden danger of high-speed rail transportation. The high-speed train passes near the station building. So the train may derail and hit the station building. Building a high-speed railway station usually uses a reinforced concrete structure. As a result of high impact energy on the impact body, the reinforced concrete (RC) member may fail; the impact point is near the member's foot; the structural member's constraint can be considered fixed support. This paper investigates the dynamic behavior of four types of circular reinforced concrete members under unequal lateral impact loads. The RC member's failure mechanism and dynamic response addressed the significance of unequal lateral impact load. The usual circular reinforced concrete members are used as the model to perform the drop-weight impact test. The specimens' crack pattern, failure mechanism, impact, deflection, and strain time–history curves are obtained. Findings show that between the impact point and the adjacent support, shear fractures occur that fail in shear mode. Shear cracks are based on impact velocity, longitudinal reinforcement ratio, and stirrup ratio. One type is more destructive to members and nodes. A shear fracture occurs when a longitudinal reinforcement fractures towards the closer support. The effects of impact velocity, longitudinal reinforcement ratio, and stirrup ratio on the dynamic impact response are studied. The experimental results may help improve structural member impact resistance. The critical section (right side) computed the static shear resistance using shear force, whereas the maximum external load resistance determines static bending moment resistance. Understanding how circular members fail to be subjected to unequal lateral impact loads provides insight into circular RC members' impact design and damage evaluation.
