The 1986 AISC 'Load and Resistance Factor Design (LRFD) Specification for Structural Steel Buildings' includes new rules affecting the design of built-up members composed of rolled shapes. These rules are based on the result of recent studies which indicate that the connector spacing has a direct effect on the strength of a built-up member buckling out of the plane that separates the individual members. Various test results have provided the necessary information to develop a formula for a 'modified' slenderness ratio.
