Factor in Load and Resistance Factor Design
Publication: Journal of Structural Engineering
Volume 113, Issue 8
Abstract
The linear approximate expression for the factor used in the American Institute of Steel Construction's 1986 load and resistance factor design specification is derived on the basis of an in‐plane elastic beam‐column analysis. This expression is assumed to be conservative for the design of beamcolumns in the inelastic range, in plane and in space. In this paper, the validity of these assumptions is examined closely for box‐ and I‐shaped cross sections under uniaxial and biaxial loading conditions. It is found that the linear expression without the condition is valid for beamcolumns in plane and in space, and provides a close approximation to the exact results based on the inelastic analysis of an imperfect beam‐column, just as that based on the elastic analysis does.
