Registration Date 06-01-2025 Organization Metinvest Polytechnic Technical University, Limited Liability Company popup.description1 To determine the techno-economic efficiency of using bent-welded reinforcement profiles compared to closed bent profiles by evaluating changes in the operational characteristic of stiffness and substantiating the possibility of reducing material consumption through the reduction of profile wall thickness popup.description2  The purpose of the work is to establish the technical and economic efficiency of using bent-welded reinforcing profiles compared to closed bent profiles by assessing the change in such an operational characteristic as rigidity, and to substantiate the possibility of reducing the material consumption of their manufacture by reducing the wall thickness of the profiles. The object of the study is closed bent and bent-welded steel reinforcing profiles. The subject of the study is the operational characteristics, material consumption and technological aspects of manufacturing steel profiles of various types. Information on implementation: the results of the research work were transferred to the customer - PP "DANVIS" according to the acceptance and transfer certificate dated "20" December 2024. The work performed satisfied the customer. The results of the work can be useful in practical activities for the development and planning of the production of reinforcing bent profiles for certain window systems, the selection of wall thickness depending on the loads. Given the current requirements of martial law, the wall thicknesses of the profiles must take into account the presence of impulse and explosive loads. The results can be useful in the educational process when teaching in educational programs in the following areas: 13 Mechanical Engineering = G Engineering, Production and Construction, namely 136 = G10 Metallurgy and 131 = G9 Applied Mechanics. Scope: metallurgy, construction, production of window systems, structures of load-bearing elements, research work, educational programs.
