“…Research in the mid-1970s indicated that keeping h fixed and increasing p has important gains, although this type of implementation is less general than the h-method (Szabó, 2014), and is known to require larger RAM memory and amount of calculations (thus involving a higher CPU time) in the FEA of metal-forming processes (Cannizzaro et al, 1988). However, it was proven that if the mesh is properly designed, the error of approximation goes to zero exponentially as p increases (Szabó, 2014).…”

Purpose – Since the use of advanced finite element analysis (FEA) in the design of steel structures has been increasing its popularity in order to avoid unsafe or highly conservative designs, a solid know-how in computer-aided design (CAD) and engineering (CAE) codes is necessary. Therefore the purpose of this paper is to provide an extensive review of useful guidelines concerning modelling, simulation and result validation for the accurate performance of those analyses. Design/methodology/approach – Such guidelines are obtained from international steel design codes like Eurocode 3 and DNV, publications from experienced CAE engineers and renowned FE software companies like Ansys and Altair. Topics like mesh independence, the effect of the load sequence on the load bearing capacity and steel fracture criteria are underlined. Findings – Since the use of advanced FEA in the design of steel structures is becoming more and more traditional due to the increase of its competitiveness when compared to the use of (very) conservative design rules, a solid know-how in CAD and CAE codes is necessary. Practical implications – This work will be quite useful for structural steel stress engineers, contributing for a safer use of FEA in research and design. Originality/value – This work will be quite useful for structural steel stress engineers, contributing for a safer use of FEA in research and design.
