The paper discusses the stability behaviour of large angle columns in high strength steel subjected to compression loads. It presents a number of compression tests on such columns that have been performed at University of Liege with different eccentricities and slenderness and, as a result, different buckling failure modes observed. The experimental campaign is intended to widen the knowledge about the behaviour of high strength steel columns with large angle sections in compression and bending and so to complement previous experimental studies. The tests have been accompanied by numerical analyses and calculations of the load carrying capacities through present Eurocode prescribed methods. The numerical simulations have been carried out by application of the FEM software FINELG using beam elements and considering of relevant imperfections as well as geometrical and material non – linearities. The numerical and analytical results are compared and validated with the corresponding experimental ones and summarized in the present paper. The experimental campaign and the numerical simulations are part of the European‐funded RFCS project ANGELHY “Innovative solutions for design and strengthening of telecommunications and transmission lattice towers using large angles from high strength steel and hybrid techniques of angles with FRP strips”.
