The aim of this mini-symposium is to provide a forum for the presentation and discussion of the most recent developments and future trends in the fields of mechanical behaviour, numerical simulation and experimental testing of steel structures, commonly encountered in civil engineering applications. Regarding the mechanical behaviour of steel structures, several topics of interest are addressed, including non-linear static, stability (buckling and post-buckling), plasticity, monotonic and cyclic, fatigue, fire, dynamic and impact. Moreover, new developments of computational methods for the analysis of steel structures are welcome, including (but not limited to) the finite element method, finite strip method and generalised beam theory. Specific topics will include, among others: steel members (columns, beams, beam-columns); steel connections; steel structural systems (trusses, frames, arches, towers, tubular structures); thin-walled steel structures; plated steel structures and shells; hot-rolled, cold-formed and welded steel structures; mild steel and high-strength steel; stainless steels. In resume, theoretical, numerical and experimental contributions are welcome, as well as research work aimed at improving current steel design codes.
