Resumo: The main purpose of the investigation presented is the characterisation of the nonlinear cyclic behaviour of steel joints between I profile beams to hollow section columns with welded reverse channel. When compared with other steel shapes, tubular profiles show a privileged structural behaviour due to their ability to withstand axial loads, bending in several directions and torsion, besides considerable advantages in terms of maintenance and aesthetics. The welded reverse channel connection is a good solution since it allows for a bolted joint between I beam to hollow column. Furthermore, this type of joint detail has a reasonable construction cost, is easy to implement and possesses large ductility through the deformation of the web panel. In this paper a comparison is made between experimental and numerical finite element model results. The main focus will be on the results concerning the main components of the reverse channel, i.e. web face in bending, flanges panels in shear, compression and tension. The main objective of these tests is determining the strength, stiffness and rotation capacity of the main components of the reverse channel joining detail. In the experimental program the characteristics of the nonlinear behaviour of the principal reverse channel components is assessed by means of bending tests (monotonic and cyclic). The parameters which have been varied in the tests are the geometry of the loaded area and the dimensions of the flanges and web of the U shaped element. The numerical models are developed in the software LUSAS and calibrated with the results from the experimental tests.
