Evaluating Single Angle Compression Struts Using An Effective Slenderness Approach

Lutz, Leroy A. (2006). "Evaluating Single Angle Compression Struts Using An Effective Slenderness Approach," Engineering Journal, American Institute of Steel Construction, Vol. 43, pp. 241-246.

This paper describes a simple procedure for evaluating the capacity of single angle compression struts that are supported at each end by one leg to a gusset plate or directly to a leg or stem of the chord of a truss. This procedure allows the single angle to be treated for analysis and design as a pinned-end axially loaded compression member by use of an effective slenderness ratio. The procedure considers two levels of end restraint and addresses both equal and unequal-leg angles. This procedure has been added for use in the 2005 version of the American Institute of Steel Construction Specification for Structural Steel Buildings (AISC, 2005).
