Estudio de viabilidad de estructuras de madera para infraestructuras de transporte

Abstract

Este trabajo desarrolla un estudio aplicado a las modernas infraestructuras de transporte para el caso específico de un puente arco con tablero inferior vehicular de madera, teniendo en cuenta las normativas, así como la experiencia real de un puente ya ejecutado en estructura mixta de acero y hormigón que se encuentra ubicado en Sant Andreu de la Vola, Barcelona. Para ello se han definido las características geométricas y las propiedades mecánicas de los elementos estructurales de madera consistente con la normativa de diseño en estructuras de madera. También se analizaron las tipologías de puentes de madera susceptibles de cumplir con las características físicas del puente real que se requiere estudiar como modelo, con la finalidad de adaptarse a las condiciones existentes del puente y a condiciones estructurales y viables, al objeto de viabilizar y optimizar dicho puente de madera. Se modeló un puente arco de madera en el programa SAP2000 para optimizar las secciones requeridas de madera que pueda soportar las cargas estructurales a las que estaría sometido el puente vehicular. A la vez, se modeló el mismo puente, pero construido con acero para poder hacer las comparaciones en cuanto a costos y asimismo la cantidad de emisiones a lo largo de su ciclo de vida con respecto al puente de madera.

This work develops a study applied to modern transport infrastructures for the specific case of an arch bridge with a wooden vehicular lower deck, taking into account the regulations, as well as the real experience of a bridge already executed in a mixed steel and concrete structure which is located in Sant Andreu de la Vola, Barcelona. For this, the geometric characteristics and mechanical properties of the wooden structural elements have been defined, consistent with the design regulations for wooden structures. The types of wooden bridges capable of complying with the physical characteristics of the real bridge that need to be studied as a model were also analyzed, in order to adapt to the existing conditions of the bridge and to structural and viable conditions, in order to make viable and optimize said wooden bridge. A wooden arch bridge was modeled in the SAP2000 program to optimize the required sections of wood that can withstand the structural loads to which the vehicular bridge would be subjected. At the same time, the same bridge was modeled, but built with steel to be able to make comparisons in terms of costs and also the amount of emissions throughout its life cycle with respect to the wooden bridge.
