Sijinio tilto sijų efektyvumo daugiakriteris vertinimas / ; Multicriteria evaluation of beam bridge beam efficiency.
Summary The aim of the final project is to perform a multi-criteria evaluation of the efficiency of beam bridge beams. The objectives of the project are to analyze the main types of bridges, to study the technologies of beam bridge construction, to analyze the materials used in Europe and Lithuania, to perform a multi-criteria evaluation of beam bridge girder efficiency using SAW (Simple Additive Weighting) method. The final project consists of 3 parts. The first is the analysis of scientific articles, the second is the analysis of the SAW method, and the third is the multicriteria evaluation of beam bridge beams. The theoretical part analyzes the bridge girder, arch, cable, cable, truss and wooden bridges, their constructional schemes, describes the underground elements, above-ground elements, their supporting elements and the structural schemes themselves. Further in the work, more attention is paid to the structural analysis of beam bridges. Technologies and abundance of pole foundations, grate, torso / columns, beams, support cushions, support bearings, beams, and deck decking were reviewed. Materials used in the construction of beam bridges, such as steel reinforcement, fiberglass reinforcement, concrete and its additives, were also investigated. Material comparison tables have been compiled. An analysis of the consistency of the experts' opinions was carried out, where certified specialists working with bridges and roads were interviewed, who expressed their opinion on the importance of the evaluation criteria for the beams. A computational scheme of a beam bridge has been developed. Using Robot Structural Analysis Professional 2019, the loads acting on the most exploited beam were calculated and rational beam profiles were selected. 6 floor elements were compared in the work: 2 double type steel profiles - HEA700 and HEB500, 2 T-shaped concrete beams, one of which is reinforced with steel, the other with glass-basalt fiber reinforcement and 2 concrete floor slabs, one of which is reinforced with steel, ...
