"In the design of steel buildings, the "Allowable Stress Design (ASD)" method has long been used for cold-formed steel structural members in the United States and other countries. In this approach, member forces, or moments, determined on the basis of working loads should not exceed the allowable values. The allowable value is used to prevent the possible structural failure by using an appropriate factor of safety selected primarily on the basis of engineering judgment and long-time experience.

Recently, in the United States, the concepts of risk and reliability analysis have been successfully applied to the Load and Resistance Factor Design criteria for steel buildings using hot-rolled shapes, and built-up members fabricated from steel plates.

In order to develop reliability based design criteria for cold-formed steel members, a, joint research project entitled "Load and Resistance Factor Design (LRFD) of Cold-Formed Steel" was conducted at the University of Missouri-Rolla, Washington University, and the University of Minnesota. This study included the selection of a reliability analysis model; the evaluation of load factors; the calibration of the design provisions; the determination of resistance factors; the comparative study of design methods for cold-formed steel; and the preparation of the LRFD design manual for cold-formed steel. However, only the development of the reliability based design criteria, and the comparative study of design methods for cold-formed steel are discussed in this dissertation"--Abstract, page iii.
