Cross-sectional stability of wide flange structural steel columns at elevated temperatures



Mina S. Seif, Therese P. McAllister


There is a lack of understanding of how structural systems perform under realistic, uncontrolled fires. Fire protection of steel structures is usually provided through prescriptive requirements. The development of performance-based standards and tools require explicit consideration of fire effects on structural components and systems. This paper presents a parametric study employing nonlinear material and geometric finite element analyses to model the response of wide flange steel column sections at elevated temperatures. The parametric study varied the axial load and cross- sectional slenderness of three lengths of column sections. The column sections were uniformly heated until they exhibited either nonlinear or elastic buckling failure. Computational results illustrate the relationship between local slenderness in the web and/or flanges and the local and global buckling modes under varying load and temperature conditions.
