摘要

The paper deals with the cyclic behaviour of bolted aluminium T-stub joints. Quasi-static loading tests, which have been carried out within a general research project aiming at setting up useful design procedures for aluminium alloy structural joints, are presented. The experimental campaign is related to 26 different welded specimens coupled either to each other or to a rigid support by means of aluminium and steel bolts. In particular, 4 different T-stub joints (varying in-plane dimensions, plate thickness, number and location of bolts), 3 different aluminium alloys as flange material and 3 different types of bolt have been considered. The obtained results allow the influence of the above parameters on the observed failure plastic mechanism as well as on the deformation and dissipative capacity of the examined joint type to be pointed out.
