description: The research set the following goals:
1. Study, generalization and analysis of the experience of using and designing lightweight beam structures;
2. Study and analysis of the behavior of lightweight girder structures under the same load using the LIRA software package and analytical calculation methods;
3. Choosing the optimal design based on the calculations made;
4. Providing recommendations and instructions for the design, manufacture and installation of the optimal structure.
The experimental part of the work was carried out using the LIRA software package, as well as using analytical calculation methods. 3 models were created with cross-section characteristics selected based on the maximization of one of the parameters (deflections, normal and tangent stresses). The results of various methods were compared in order to identify errors. In the future, a comparative analysis of the metal content of the following beam structures was made: composite welded, corrugated, and perforated beams. The most cost-effective design is identified and recommendations are given in the field of technologies for its design, manufacture and installation.
