Diseño de un puente de hormigón pretensado en volados sucesivos : comparación de diseño y costo de construcción entre el puente diseñado y el puente construido en Acero y Hormigón potesando sobre la quebrada de Gualo

摘要

Prestressed concrete in segmental bridges built by the cantilever method have been established in many countries as the best option for building bridges with lengths between 60 and 320 meters. This technology uses in an optimum way the specific properties of the steel and concrete. In this paper the structural design of a bridge two hundred meters long and a maximum spam of 98 meters was developed, the design was made in segmental prestressed concrete and considering the cantilever method for its construction. The author considered all the elements of the bridge in the design, foundations, abutments, piers, box girder, prestressed cables, etc. were designed in this paper.
