CONSTRUCTIVE DECISIONS OF STEEL BEAMS MADE OF THIN-WALLED COLD-FORMED PROFILES

Abstract

The article considers the worked out optimal variant of a constructive design for a steel covering beam having a compound cross-section made of thin-walled cold-formed sections. Numerical studies have been carried out for various options of beams taking into account reduction of cross-section. Tests were made of the created an optimal variant of a beam in full size.
