In this thesis, an analysis of hybrid beams in vehicular bridges with spans of 50m in Ayacucho was carried out, considering the alternative design in the superstructure of composite section with homogeneous beams of conventional steels that is the existing project versus the hybrid beams with A709 Grade steels. 50 and Grade HPS-70W, which will determine which is the design alternative that provides the best results from the point of view as a technical and economic proposal. Six chapters are developed for this analysis. Chapter number one describes the work plan to follow to achieve the objectives set. The second chapter includes the theoretical framework in which the concepts, classification of bridges, types of structural steels, properties, regulations and design philosophy are defined. In the third chapter, the case study applied to an existing project is carried out, where we use the background and information of the project. In the fourth chapter, the modeling and results of structural analysis are carried out; In this chapter, the SCibridges software is used to calculate the demands on the structure. In the fifth chapter, the design of the beams is carried out in which material tests of a sample of HPS 70W grade steel are presented, likewise, the I-beam design is carried out according to AASHTO LRFD where considerable results are obtained to reduce conventional steels. Finally, chapter six presents the conclusions and recommendations aligned to the objectives set.
