Abstract

This article is devoted to the study of the possibility of replacing the flat web in crane girders with a corrugated one to increase the reliability and stability of welded joints. During the research, stress analysis was carried out on structures with two types of web contours, revealing the features and advantages of corrugated webs. The article provides a detailed overview of the analysis results, demonstrating how a corrugated structure can effectively replace a flat one by improving strength, stiffness, load-bearing capacity, and stability, while simultaneously preventing weld detachment under load. The reasons for choosing this method and its practical applicability in industrial conditions are thoroughly examined. The study included a computer-based experiment involving calculations using the Tonus post-processor of the SCAD software package, as well as the LIRA-SAPR 2022 software. The stages of the experiment included the creation of a finite element model of the beam based on a physical experiment, calculations of geometric characteristics of various web shapes using the Tonus post-processor, 3D modeling of crane girders with flat and corrugated webs, computation and determination of maximum normal and shear stresses in the web using LIRA-SAPR 2022, comparison of results for beams with flat and corrugated webs, interpretation of the results, and justification of conclusions based on the obtained data. The authors highlight the potential applications of this approach in various industrial sectors, emphasizing its importance for ensuring the safety and durability of crane girder structures. The results obtained serve as a foundation for further research and the practical implementation of innovative solutions in the design and operation of industrial structures.
