![]() It is crucial to conduct initial assessments of practical applications to quantify ship hulls’ maximum load-carrying capacity or ultimate global strength for economic and safety reasons. A variety of stiffeners are usually built-in, such as flat bars (FBs), L-sections, T-profiles, I-profiles, etc. ![]() Stiffeners are assembled in the longitudinal or transverse direction and equally spaced over plates to ensure the strength and durability of the ship’s structural components. The reinforcement of thin-walled structures with lightweight stiffeners is a better method in most cases compared to increasing the web thickness of an unstiffened plate. These structures are formed of an arrangement of plates/shells reinforced with stiffeners. Stiffened panels are essential structural elements that form the primary structures of ships and other maritime vessels. Most thin-walled designs in ship structure applications are stiffened for structural, weight conservation, and cost-effectiveness reasons. The use of thin-walled steel structures has generally increased over the last few decades, with their areas of application becoming increasingly diverse, ranging from ships to other marine platforms. In terms of the plate design, the stiffener is observed to reduce the force expansion during the loading of the stiffened plate. The results indicate that increasing the loading angle reduces the force experienced by the plate, while the greater the loading direction angle is, the greater the total displacement value will be. A geometrical design is adopted based on the side hull structure of a medium-sized tanker, for which two plate types, unstiffened and stiffened, are used. type and angle) are taken as the main inputs in the finite element analysis. low- and medium-carbon steels – and loading parameters (i.e. In this work, we attempt to obtain the behaviour data of unstiffened and stiffened plates as components of thin-walled structures. In this situation, assessments are required to quantify the responses and determine the relationships between the structural behaviour and structural parameters. Deformation patterns and overall behaviour are expected to be varied, as different materials are considered in the structures. Due to environmental conditions and working operation, the components of the structure unavoidably become subject to various types of loading. ![]() Thin-walled structures, which generally consist of unstiffened and stiffened plates, are widely used in engineering as one of the core features of any product or construction.
