Abstract

This paper presents an experimental investigation of the inelastic behavior of wide-flange structural steel members under combined time-dependent bending and torsional loading. A quantitative evaluation of energy dissipation capacity after occurrence of local buckling was made. Test results show that a W6xl5 section with a d/bf ratio equal to one performed better than a WSxlO section, which has a larger d/bf ratio, in resisting combined bending and torsion. Test results also show that the presence of torsion significantly affects a member's bending-moment carrying capacity. Introduction Current design philosophy for structural systems requires that structures must be sufficiently ductile to prevent collapse during major earthquakes. Steel structures hav
