Can develop its full plastic moment capacity, but has limited rotation capacity due to subsequent local buckling. Semi-Compact DL + EL | 1

Utilizes Load and Resistance Factor Design (LRFD), which is the American equivalent to Limit State Design.

Material strengths can vary due to manufacturing tolerances, workmanship, and geometric imperfections. The design strength ( ) is calculated by dividing the characteristic strength ( ) by a partial safety factor for materials ( γmgamma sub m

For in-depth study, the following textbooks and standards are industry benchmarks:

LSD applies separate safety factors to the loads (actions) and the material strengths. This dual-factor system delivers a more uniform level of structural safety across different loading scenarios. Load Factors ( γfgamma sub f Loads are multiplied by partial safety factors greater than
