5. Conclusions The study presented the results of an experimental test on a triangular hollow flange beam of welded plates with different thicknesses. Considering the material properties, the flexural capacity was reached before buckling occurred. The instability of the beam can be related to the null rigidity in the moment deflection curve. The automated welding process can provide fast, strong welds for such beams. Numerical studies are required to assess the type of buckling for the studied solution. Nevertheless, a parametric study is necessary to conclude the influence of the inclined steel plates position, a minimum height of the triangular area, and compactness of the flanges.
