摘要：

The stability of columns made of large angle profiles in high strength steel and subjected to centric and eccentric compression loads is investigated through experimental tests, numerical simulations and normative approaches. The aim is to widen the knowledge on such columns and so to complement previous experimental studies that focusing on smaller angle profiles and lower steel grades. The experimental campaign consists of twelve tests. Accompanying numerical studies have been carried out, considering relevant geometrical imperfections as well as geometrical and material non-linearities. Finally, an assessment of the design member resistance according to Eurocodes has been performed. It is further discussed.
