“…The CSM has now been applied to the design of steel [3,4], stainless steel [5][6][7][8], aluminium alloy [9,10], reinforced concrete [11] and composite structures [12,13], as well as steel structures in fire [14,15]. Recent attention has been focussed upon extension of the CSM to member-level design [16][17][18][19] and incorporation of the CSM into a framework of design by advanced analysis [20][21][22][23] and into codes of practice; the CSM now features in the AISC Design Guide for Structural Stainless Steel (2013), the fourth edition of the SCI Design Manual for Structural Stainless Steel (2017), the draft prEN 1993-1-4 for the design of stainless steel structures, the draft prEN 1993-1-14 for the design of steel structures by finite element analysis, the ASCE Specification ASCE-8-21 for the design of cold-formed stainless steel structures and the AISC Specification AISC 370 for the design of hot-rolled and welded stainless steel structures. A review of the background, key concepts and components, and fundamental design equations of the CSM is presented in this paper.…”
