Xu, M.C. and Guedes Soares, C. (2012), “Numerical study of the effect of geometry and boundary conditions on the collapse behaviour of long stiffened panels”, Maritime Engineering and Technology, Guedes Soares, C., Garbatov, Y., Sutulo, S., Santos, T.A. (Eds.), Taylor and Francis Group, pp. 415-422
The FE model and boundary conditions are both affect the collapse behavior of stiffened panel. The 120 specimens with different boundary conditions and models are simulated to analyze the influences of the stiffener’s geometry and panel boundary conditions on the ultimate strength of long stiffened panels under compression. The long stiffened panels analyzed with four type stiffeners are made of mild or high tensile steel and have bar, ‘L’ and ‘U’ stiffeners. From the results of the FE analysis, two of the four models studied can produce adequate boundary conditions at the loaded edges. The stiffened panels with different combinations of mechanical material properties and geometric configurations are considered. The initial geometric imperfection affects the collapse behavior of stiffened panel and is analyzed in FE simulation.
