Desarrollo y análisis de tablero para puentes vehiculares formado por vigas-cajón de 12, 15 y 18 metros de luz

Abstract

The bridges always have been one of the structures in the Civil Engineering most important and needless. Is very important the easy construction. Generally in Ecuador the bridges construction between the 10 to 20 meters to span, use slab concrete bridges. The next investigation show a typology frequently used in other countries as is the board bridges formed by box-beams. Is very important to say that our in country there an important bridge with this typology, Iberia Bridge with multiple spans of 14 meters. The following work took about the methodology of design of the of the board bridge consisting of box-beams; resumethe knowledge that should be taken for the right and functional development, for this reason we start the design of a beam reinforced of12, 15 and 18 meters of span and finally the use of the transversal post-tensioned to get the development of a monolithic structure. At a time to do excel spreadsheets of each one of the components that make up the board, all this analysis compares with the Software Finite Element Analysis SAP2000. All the analysis shall be proposed according to the features, specifications and needless of the construction, take advantages of it.
