“…To investigate the influence of stiffener geometry on the ultimate strength of the stiffened panels under compression, eight tests of eight three-bay stiffened panels with associated plate made of very high tensile steel S690, were conducted by Gordo and Soares [143]; following this the same authors performed an extended experiment on long stiffened panels under axial compression until collapse, in order to study the effect of space framing on the strength of stiffened panels [144]. Four types of stiffened panels with three bays longitudinally were made of mild or high tensile steel for To investigate distortional buckling, and the interaction between local buckling and distortional buckling of longitudinally stiffened plates, Kwon and Park [147] carried out a series of compression tests on longitudinally stiffened plates made of mild steel SM400. The compression tests indicated that the critical buckling mode was dependent mainly on the rigidity of the longitudinal stiffeners and the width-to-thickness ratio of the sub-panels.…”

Stiffened panels made out of isotropic or anisotropic materials are being extensively used as structural elements for aircraft, maritime, and other structures. In order to maintain stiffness and strength with light weight, new design techniques must be employed when utilising these materials. Their stability, ultimate strength and loading capacity are the key issues pertaining to these engineering structures which have attracted a number of investigators to undertake in- depth research, either in an academic or actual engineering context. This paper provides an extensive review of the research which has been conducted in recent years (2000-2012) on the buckling and post-buckling response of isotropic and composite stiffened plate and shell structures related to analysis and experiment. The key objective of this review article is to collate the research performed in the area of buckling and post-buckling behaviour of stiffened structures, thereby giving a broad perspective of the state-of-the-art in this field.

“…The main dimensions of the perforated plate were length (a), breadth (b), thickness (t), opening in the plate length direction (L), opening in the plate breadth direction (D), axial displacement (U), and lateral deflection (w). To investigate the lateral deflection characteristics of the perforated plates, we considered three variables-opening size (D/L), thickness (t), and aspect ratio (a/b)-on the basis of previous studies and actual shipment data [3,[11][12][13]. From the previous reference data, the dimensions of the plates used in shipbuilding industries are in the following range: aspect ratio (1.00-6.55), slenderness ratio (1.42-3.83), breadth (800-975 mm), thickness (10-22 mm), opening size (400 mm × 600 mm, 500 mm × 700 mm, 600 mm × 800 mm), and opening ratio (0.44-0.83).…”

This study aimed to investigate the behavioral characteristics of the lateral deflection of a simply supported perforated steel plate subjected to axial compression. Investigating the lateral deflection of the perforated plate is of great significance because the buckling limit of structural members can be predicted not only by strength but also by displacement (or deflection). For this purpose, we conducted buckling experiments by considering various variables of the perforated plate, such as opening size, thickness, and aspect ratio. In addition, a series of elastoplastic large deflection analyses were performed using the commercial finite element analysis program, and the calculated results were compared along with the experimental results. Finally, practical curves, which can predict lateral deflection with an increase in axial displacement, and the occurrence point of ultimate strength are reported in this study. The results showed that there was a distinct difference in the behavior of lateral deflection between perforated plates with different opening ratios. The local buckling occurred mainly around the opening and was more dominant with an increase in the opening ratio. In addition, the ultimate strength of the perforated plate was determined at the end of the local buckling phase.

Cellular plates are constructed from two face plates and a stiffener grid welded between them. It is shown that the square cellular plates can be calculated as isotropic ones. Therefore, the classic formulae for maximum bending moment and deflection, valid for isotropic plates, can be used. The stiffeners can be made from halved rolled I-profiles, or from welded T-sections. These two kinds of cellular plates are optimized, and their minimum volumes and costs are compared to each other. The comparison shows that the cellular plate with welded T-stiffeners is more economic.
