Abstract

This paper presents formulae and procedure to determine geometrical properties of a mono-symmetrical I-section beam with hollow flange; this is an opened-closed section. Then the expressions of flexural-torsional buckling can be applied to obtain critical moments. The comparison of critical moments between the symmetrical I-section and the mono-symmetrical I-section shows the efficiency of the hollow flange.

Keywords: Flexural-torsional buckling; opened-closed section; shear center; sectorial coordinates; warping constant; torsion constant; uniform and non-uniform torsion.
