Abstract Hollow section steel profiles are widely used for industrial purpose. Next to circular hollow section, which are set to for example offshore constructions, squared hollow section profiles have many advantages. The profiles are lightweight, have got a high rotational stiffness and in contrast to circular profiles, squared profiles can be welded more easily without having multiplanar welding radii. The weakest point of columns with two or more members is the node. Due to the geometrical heterogeneity and the imperfection due to the process of welding it is a complex part to calculate. This paper is about a numerical case study of a full-overlapped squared hollow section joint. A focus is the influence of the inclination angle on the maximum stresses and deflection in the ultimate limit state. The analysis is split into symmetrical and asymmetrical structures. The aim is to figure out the influence of the inclination angle on the stability of the joint.
