Abstract

"This dissertation describes the development of the basic criteria needed for the design of structural members cold-formed from certain ferritic stainless steels. The Allowable Stress Design method as well as the Load and Resistance Factor Design method receive attention. The ferritic stainless steels under consideration are: Types AISI 409 and 430 as well as a modified Type 409 steel, designated 3CR12 steel, developed and produced by the speciality steel producing company, Middelburg Steel and Alloys in South Africa.

The mechanical properties needed for structural design are established. It is shown through an experimental study that the design provisions for the carbon and low-alloy steels as well as those for the austenitic stainless steels, are suitable for the ferritic stainless steels in as far as local and post buckling behavior of flat stiffened and unstiffened compression elements of member sections are concerned. Investigations into the behavior of flexural members and axially loaded compression members indicate that aspects such as ultimate moment capacity and deflection of flexural members and overall column buckling of compression members may be predicted with confidence. The performances of bolted and welded connections are also evaluated. The experimental results are statistically analyzed to provide the information required for the development of resistance factors for the Load and Resistance Factor Design Method.

The needs for future research are identified"--Abstract, page ii.
