FEA of steel structures

What is it about?

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 this paper provides an extensive review of useful guidelines concerning modelling, simulation and result validation for the accurate performance of those analyses. 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 (i) mesh independence, (ii) the effect of the load sequence on the load bearing capacity and (ii) steel fracture criteria are underlined.
