LRFD aid for tubeshaped beams

Abstract

This paper presents design tables as supplement to Load and Resistance Factor Design Specification for Structural Steel Buildings (LRFD). The tables would greatly facilitate the selection of tubular flexural members and would complement the existing beam design aids available for other rolled shapes in the LRFD manual. The design aid information available is valid for tubular sections used as beams. It is assumed that the loading is applied in the plane of the minor axis and that the beam deflects vertically in the plane of bending only. This paper uses the same nomenclature as the LRFD manual.
