Modified Slenderness Ratio for Built-up Members

Sato, Atsushi; Uang, Chia-Ming (2007). "Modified Slenderness Ratio for Built-up Members," Engineering Journal, American Institute of Steel Construction, Vol. 44, pp. 269-280.

Based on a review of theory, background for the historical development of the AISC specifications, and an updated experimental database, a simple model which maintains the accuracy for the calculation of the modified slenderness ratio of built-up members with closely spaced individual components (for example, double angles and double channels) that are connected by welded or pretensioned bolted connectors is proposed.
