Abstract:

Steel I-section-plate girders with corrugated webs have been used worldwide as they provide more stability and light beam features in practical design. It is known from previous investigations that due to having numerous favourable properties, the corrugated-web beams have been used in different areas of structural engineering. Considering the raising popularity of using CWBs in steel design, some practical aspects of CWBs need to be investigated further, in which post-buckling strength is one of the most critical strengths that should be precisely estimated. To fulfill this requirement regarding the post-bucking strength determination for structural designers community, a numerical investigation has been conducted in this study to determine the moment capacity reduction factors for steel I girders with corrugated-web profile and to compare reduction factor values extracted from EN 1993-1-5 (Design of steel structures part 1–5: Plated structural elements, Eurocode 3, Brussels, 2006), AS4100 (Steel structures, Standard Australia, Sydney, 1998), and finite element analysis. Theory of Ultimate Limit State design has been adopted in accordance with AS4100 (1998) along with considering geometric and material non-linearity in the numerical analyses in SAP2000 software. Eventually, the results of the parametric study have been compared and discussed leading to presenting practical recommendations on the design of CWBs for bending strength.
