Title of the articleSteel truss with chords of multi-faceted cross-section tubes
Abstract.Most popular structures of steel trusses in some cases do not have an economic efficiency including maintenance costs. Nowadays, steel multi-faceted cross-section supports of power line have found wide uses in the power industry. This article is about using of galvanized multi-faceted cross-section tubes as chords of steel trusses. The authors offer new solutions of multi-faceted cross-section to form a joint plate. The article considers the search of the most rational shape of multi-faceted cross-section. The authors propose constructive solutions of trusses with chords from multi-faceted galvanized tubes of variable section along the length, and braces from galvanized profiles of constant section along the length which attached by bolts to the joint plate. To confirm the possibilities and efficiency of multi-faceted cross-sections in chords of trusses, by the methods of comparative analysis, computer simulation and variant design carried out researches. As a result of research the most rational form of multi-faceted sections, designed assortment, set the efficiency of their use as a chord of trusses are found.
Keywords.steel trusses, multi-faceted cross-section, joint plate, galvanize surfaces, tube, supports of power line, chord of truss.
