## 1 Introduction  
Currently, it is estimated that nearly 90% of global goods are moved via maritime transport, with around 60% of those being shipped in containers. This highlights the crucial role that container vessels play in both the maritime logistics chain and the global economy. These ships are specifically designed to enhance the efficiency of loading and unloading processes at ports. However, they are particularly vulnerable to bending and torsional stresses. Container vessels feature double bottoms and are framed longitudinally, making this section especially critical when assessing structural integrity [1]. A key component of the double-bottom structure is the transverse elements, often referred to as floors. Inspection ports, pipe tunnels, weight-reduction cutouts, and apertures that let regular stiffeners from the bottom and double bottom pass through are features that set these constructions apart. Due to the significant concentrations of stress in this location, a mix of these characteristics impacts the structural capability of the floor [2]. The floor can be treated as reinforced panels or perforated plates for structural analysis, where the buckling strength of the plates is decreased by the cutouts and perforations. The buckling design process needs to take this reduction into consideration. This kind of construction has been extensively studied from a variety of angles. [PERSON] et al. [3] used both linear and nonlinear FEM models to examine how geometrical parameters affected buckling and ultimate strength. Additionally, they suggested a simplified method that accounts for reduction factors. Through experimental and computational research, [PERSON] et al. [4] shed important light on how large and small apertures affect the ultimate strength of transverse and longitudinal girders with uniaxial and lateral pressures on plates located on the main deck. Apertures' geometry is crucial for structural assessments. This is illustrated in the study by [PERSON] et al. [5], which examined how the final strength of steel panels that had undergone compressive testing after being stiffened and unstuffened was affected by variations in opening size, shape, steel composition, and structural configurations. Similarly, [PERSON] et al. [6] investigated the effects of size, opening position, and form on bending-plate buckling strength. [PERSON] et al. [7] expanded their study by incorporating a new variable and investigating the effects of different morphologies--circular and extended circular openings--with loads in one direction using a range of high-strength steels. Because of their susceptibility, these structures require sufficient reinforcement to remain structurally sound for the duration of their useful lives. As a result, significant research has been directed at this issue. For instance, [PERSON] et al. [8] developed a formula for this design approach after investigating the best reinforcement strategies to improve perforated plates' buckling and ultimate strength. Another important consideration when examining these structures is corrosion. [PERSON] and [PERSON] [9] examined how effectively the integrity of a deteriorating structural model can be restored. The study applied both uniaxial compressive forces and the effects of irregular, intermittent corrosion degradation to this manhole-shaped girder. Similarly, [PERSON] and [PERSON] [10] assessed the usual strengthened plates' maximum compressive strength with perforations, using both numerical simulations and experimental techniques, with a focus on the impact of corrosion. In a related study, [PERSON] et al. [11] conducted experiments to determine the maximum strength of steel plates subjected to uniaxial compressive pressures and having big, extended circular holes. They looked at energy dissipation, resilience, toughness, force-displacement, strength-strain, and collapse modes. Other odd geometries have also been studied for their structural implications.
