STRUT ANALYSIS APPLIED TO STIFFENED COMPRESSION PANELS

A Perry-Robertson strut analysis is compared to elastic orthotropoc plate solutions for several initially deformed stiffened compression panels of typical cross-section, subjected to different distributions of in-plane loading. Conditions simulating the influence of longitudinal compatibility with adjacent panels, lateral constraint, shear lag and unequal end loads are considered. The influence of side ratio is considered for the case of equal uniform stress. It is concluded that the strut approach may significantly underestimate stresses involving lateral constraint, that the strut approach may not give realistic stresses in cases of varying stress due to shear lag, that a strut approach for mean stress gives reasonable solutions for cases of unequal end load for most practical eases of interest and that side ratio may affect the accuracy of strut solutions at values of length/width greater than 1.0.
