Theoretical and Experimental Study on Buckling of Built-up Columns
Publication: Journal of Engineering Mechanics
Volume 121, Issue 10
Abstract
A generalized theory is presented here for the analysis of buckling of built-up columns with end stay plates. The theory is a modification over the method presented by Atle Gjelsvik. Buckling loads are found for columns with some typical boundary conditions. Models of built-up columns were tested under axial compressive loads for different boundary conditions. The buckling loads obtained from the experiments agree quite well with the theoretical solutions. The buckling loads obtained were higher than the classical Engesser solution, which led to the conclusion that the theory presented here is an improvement over the Engesser's theory.
