Abstract

Abstract: The buckling and postbuckling response of the FML profile/column investigated experimentally and determined analytically and numerically is compared. Real dimension specimens of 3/2 FML open cross-section profiles subjected to axial compression in laboratory buckling tests have been modelled in finite element method and examined analytically based on Koiter's asymptotic theory. Buckling load obtained experimentally on the basis of strains is juxtaposed with those determined on the basis of deflection measurement and compared to analytical and numerical result values. Numerical model was improved with respect to the experimental findings.
