Web13 sep. 2013 · For this reason, the Load and Resistance Factor Design (LRFD) is the preferred method of structural steel design. LRFD method has two principle benefits over the ASD method. First, during limit state analysis, engineer does not have to presume linearity between force and load, or stress and force.
