The use of trusses designed with cold-formed C-section profiles has become popular in the country in small-scale warehouse constructions. In previous studies, the behavior of the connection of diagonal bars welded to the stiffening lip of the chord has been evaluated by means of finite elements and full-scale beam tests. In this work, the efficiency in the use of the material of these trusses is evaluated, compared to other common ones based on the same type of profiles. First, the theoretical capacity of the truss typology under study is analyzed and compared with rigid node solutions using gusset plates and with diagonal angle beams welded directly to the chord. Finally, new finite element models of theoretical beams are analyzed to evaluate the incidence of the geometric eccentricity that occurs in the nodes in the plane of the truss.
