“Large scale bending tests of spiral welded steel tubes”, EUROSTEEL 2014, Naples, Italy, September 10-12, 2014
ABSTRACT: This paper explores the results of full-scale bending tests of thick spiral welded steel tubes in the slenderness range of d/t = 73.5 to 101.5. The experimental investigations reveal unused bending capacities for such tubes compared to existent design rules and support the need for the development of improved and more efficient design recommendations. The results of the bending tests together with the investigations of the initial geometric quality of the specimens' surfaces suggest that the influence of spiral welding on the bearing behaviour is negligible in case of the investigated thick-walled specimens.
