ACCURACY OF SOME NUMERICAL METHODS FOR COLUMN BUCKLING

Various approximate numerical methods for the determination of the compressive buckling load of Euler columns are investigated. Exact expressions for the buckling load as a function of numbers of nodes or finite elements are obtained for three sets of end conditions. It is found that accuracy of the calculations depends on the edge conditions imposed as well as on the complexity of the functions chosen or implied by the method.
