Abstract:
Load and Resistance Factor Design is a major advance toward rational design of steel framed buildings. It combines the limit states of strength and serviceability with a modern probability-based approach to structural reliability. After a historical introduction, the method is defined and a generalized LRFD format developed. The discussion centers on sources of variability in design, on limit states and on probabilistic concepts underlying the numerical values of load and resistance fac-tors. The results of a design evaluation of LRFD are presented and steps are described that are being taken toward future adoption of the method into the AISC Specification.
