Title of the articleStand and test results of a 24 m span truss with elements of galvanized cold-formed profiles
Abstract.Problem statement. The purpose of the article is to determine the critical bearing capacity and deformability of the developed truss from galvanized cold-formed profiles by a span of 24 m. To carry out experimental studies, a test stand and test procedure is proposed, as well as the installation of hydraulic jacks that create the loading of the truss. Results. The tests carried out revealed the disadvantages of the truss. For the truss are developed recommendations. These recommendations relate to the design of the down chord and the increase in the weight of the test stand at place of joining the trusses. The recommendations are made and results showed us that the destruction of the truss occurred at a load 1,25 times higher than the calculated one, and the deflection does not exceed the calculated value. Conclusions. The significance of the research results for the construction industry is the developed and improved 24 m span truss provides load-bearing capacity and required deflection.
Keywords.truss from cold-formed profiles 24 m span, test stand, setting of hydraulic jacks, test methodology, test results.
