1. Introduction
The concept of cross-section classification is used in current design codes to determine the appropriate structural design resistance of metallic sections. The method limits the maximum stress in the crosssection to the yield stress fy, neglecting the beneficial effects of strain hardening. Experimental results have shown that the current design methods, based on the idealised elastic, perfectly plastic material behaviour, are often conservative in estimating the resistance of stocky hotrolled steel cross-sections in both compression and bending [1–3] and composite beams under sagging bending moments [4–6]. The Continuous Strength Method (CSM) is a newly developed deformation based approach to steel design that provides an alternative treatment to cross-section classification, and enables the effective utilization of strain hardening. The method was originally developed for stainless steel structural elements [7–9], which exhibit a high degree of strain hardening, and the same concept has since been applied to structural carbon steel [10–12] and aluminium alloy [13] design. A bi-linear (elastic-linear hardening) material model has been employed in the CSM to date, providing consistency and a satisfactory representation for design purposes of the observed stress-strain responses of cold-formed steel, stainless steel and aluminium alloys [9, 12,13]. However, due to the existence of a yield plateau, this CSM bilinear material model is less suitable for hot-rolled carbon steel. Thus, a revised CSM material model is proposed for hot-rolled carbon steel that exhibits a yield point, a yield plateau and a strain hardening region. In this paper, the application of the CSM to bare hot-rolled structural steel elements, focusing primarily on cross-sections in compression and bending, including recent developments and comparisons with test results, is outlined. Extension of the method to composite beams under sagging bending moments is then described.
