AISC - N690
Specification for Load and Resistance Factor Design of Single-Angle Members
|Publication Date:||1 January 1994|
This document contains Load and Resistance Factor Design (LRFD) criteria for hot-roiled, single-angle members with equal and unequal legs In tension, shear, compression. flexure, and for combined forces. It IS intended 10 be compatible with. and a supplement la, the 1993 AISC Specification for Structural Steel Buildings-Load and Resistance Factor Design (AISC LRFD) and repeats some common criteria for ease of reference. For design purposes. the conservative simplifications and approximations in the Specification provisions for Single angles are permitted to be refined through a more precise analysis. As an alternative to this Specification. the 1989 AISC Specification for Allowable Stress Design of Single-Angle Members is permuted.
The Specification for Single-angle design supersedes any comparable but more general requirements of the AISC LRFD. All other design, fabrication, and erection provisions not directly covered by this document shall be m compliance With the AISC LRFD. In the absence of a governing building code. the factored load combinations In A[SC LRFD Section A4 shall be used to determine the required strength. For design of slender, cold-formed steel angles, the current A[SI LRFD Specification for the Design of Cold-Formed Steel Structural Members IS applicable.
