EVALUATION OF THE BEARING CAPACITY OF A 12-METER TRUSS FROM LIGHT STEEL THIN-WALL PROFILES

The purpose of the article is to determine the maximum bearing capacity, deformations and maximum deflections of rods from cold-formed truss profiles 12 m long. The truss had changes, the bracing profiles changed, and the steel grade changed, after which it was clear that their bearing capacity and deflection were changing. For static calculation, the SolidWorks Simulation program was used. All maximum values were identified. As a result, it was shown that with a change in the section of the profile and the highest grade of steel, the bearing capacity increases by 2.4 times, and the deflection at one load has a difference of 1 mm. The results obtained show that the developed truss provides the bearing capacity and deformability.
