| Abstract | This report addresses the development of updated and unified AASHTO LRFD Specification provisions for the design of noncomposite steel box-section members. The applications include but are not necessarily limited to truss members, arch ribs and ties, rigid-frame members, columns, steel bent caps, edge girders, floor beams and steel tower legs. The types of members include rectangular or square hollow structural sections (HSS), welded or bolted built-up sections with nonslender or slender plates not containing any intermediate stiffeners, welded or bolted built-up sections with a single longitudinal stiffener within the web and/or compression flange, and relatively large sections composed of thin plates with multiple transverse and longitudinal stiffeners. The recommended provisions address the resistance of these types of members under various combinations of axial tension or compression, uniaxial or biaxial bending moment, and shear due to flexure and/or torsion. |
