The collapse of the World Trade Centre revealed problems in the design of some structural elements. It was recognized that details relating to the structural joints play a very significant role in the behaviour of structures under accidentals loads such as, impact followed by fire [1]. A very high performance of the connections is demanded to prevent fracture and a way to achieve this is to enhance the ductility and rotation capacity of the connection. In accordance with Eurocode 3, EN1993-1-8 [2], the T-stub model is used to evaluate the behaviour of the joint’s tensile components, which are responsible for assuring the ductility of the joint due to their high deformation capacity.

This paper presents a study with the aim of evaluating the behaviour of a welded T-stub component subject to static loading, at ambient and elevated temperatures, and carried out at the University of Coimbra [3]. The key variables include the …
