Abstract Due to the technological reasons in modern lightweight steel trusses, fabricated from cold-formed sections, positive eccentricities appear in the truss nodes what induce additional forces in the truss chords. To account for the real load-carrying capacity of truss node area the steel structure research in scale 1:1 were conducted. The experiments consisted of two parts: preliminary and proper one, when conclusions from the first part were applied. Carrying out preliminary studies helped to identify of the research station drawbacks and eliminate most of them, what ensure the appropriate research results. The initial numerical analysis were also conducted what was presented in the paper.

The chapter presents the results of experimental research conducted by the author in the context of the possibility of introducing a change from traditional bonding technology to an unconventional one by means of laser surface treatment. The results of the analysis of the surface condition of the materials selected for this monograph were described, both in the so-called delivery condition (after rolling) and after traditional and laser surface treatment. The chapter also provides a comparison of the energy state of the surface to be glued after mechanical, chemical, and laser treatment. The results of bonding were shown in which static strength on the joint wall was taken as a criterion of evaluation. Additionally, unusual possibilities of lasers used to create specific surface roughness and useful in bonding operations were presented.
