1 Structural Design of Stainless Steel Concrete Filled Columns Dennis Lam 1 and Leroy Gardner 2 1 School of Civil Engineering, University of Leeds, Leeds, LS2 9JT, UK 2 Department of Civil and Environmental Engineering, Imperial College, London, SW7 2AZ, UK Abstract This paper presents the behaviour and design of axially loaded concrete filled stainless steel circular and square hollow sections. The experimental investigation was conducted using different concrete cube strengths varied from 30 to 100 MPa. The column strengths and load- axial shortening curves were evaluated. The study is limited to cross-section capacity and has not been validated at member level. Comparisons of the tests results together with other available results from the literature have been made with existing design methods for composite carbon steel sections – Eurocode 4 and ACI. It was found that existing design guidance for carbon steel may generally be safely applied to concrete filled stainless steel tubes though tend to be over conservative. A continuous strength method is proposed and it is found to provide the most accurate and consistent prediction of the axial capacity of the composite concrete filled stainless steel hollow sections due largely to the more precise assessment of the contribution of the stainless steel tube to the composite resistance.
