Abstract

Naval and offshore structures are formed, basically, by stiffened plates. When under compressive loads, there is the concern about the behavior of these plates in relation to buckling. Buckling phenomenon happens in slender members that, subjected to to axial compression, when a critical load is reached, suddenly suffer a lateral deflection. Members under buckling may lose its stability before the material has reached its yield stress. The objective of this paper is to carry out, by computational modeling, a linear analysis of a stiffened plate under elastic buckling. This panel is formed by a plate and one bar-stiffener. Through a computational model developed in ANSYS® software, which is based on the Finite Element Method, a parametric variation on the plate geometry was made. Through this parametric study it was possible to evaluate the influence of increasing plate thickness, stiffener thickness and stiffener height on critical buckling load of the panel. Results show the huge influence of stiffeners on critical load.
