Design of Transversely Stiffened FRP (Fibre-Reinforced Plastic) Panels under Compressive Load

摘要

A review is made of the problem of buckling failure in fibre-reinforced plastic panels having stiffeners of hat section under compressive load acting across the line of the stiffeners. This problem is of practical importance in the design of FRP ships. Alternative analysis methods are discussed, including uses of approximate data curves and folded-plate analysis to determine initial buckling behaviour, together with nonlinear finite element analysis referring to imperfection effects and post-buckling behaviour. Some previously unreported experimental results are described. These, together with previously published test data, are correlated with theoretical analysis as a basis for making updated design recommendations.
