ABSTRACT
Linear eigenvalue analysis is carried out to determine the global buckling critical load, PCo :
The critical load PCl for local plate buckling is determined using the expression:
where k is the plate buckling coefficient that depends on the edge conditions, D is the flange plate flexural rigidity and A is the total area of the cross-section. The value of k = 1.25 represents the specific boundary conditions of the problem and gives a slight upper bound on the actual computed solution.
