Evaluación del Estado de los Puentes de Acero de la red vial Nacional de Colombia

Abstract

Este artículo pretende estudiar en detalle el estado y los daños típicos de los puentes en acero y en estructura mixta (acero y concreto) de la red vial de Colombia, sin incluir su evaluación desde el punto de vista sísmico. Basados en la evaluación del inventario y las inspecciones realizadas por el Instituto Nacional de Vías de Colombia (Invias) desde el año de 1996, a través del Sistema de Administración de Puentes de Colombia (Sipucol). El artículo se divide en dos (2) partes: en la primera se presenta una descripción de las diferentes tipologías de los puentes en acero basados en el módulo de inventario del Sipucol y en la segunda el estado y los daños típicos de los componentes principales. De los doscientos cuarenta y cuatro (244) puentes en acero que hacen parte de la Red Vial Nacional, se encontraron deficiencias estructurales, corrosión generalizada y parcial, infiltración, detallado no adecuado de las uniones, identificación de problemas de fatiga en uniones y regular calidad de las uniones soldadas. Este documento se constituye en la base para una futura y más completa investigación de estructuras vitales en la infraestructura vial como son los puentes, con el objeto de avanzar en el tema de la inspección detallada incluida la condición sismorresistente y la conservación de puentes de acero.

This paper studies in detail the state evaluation and typical damages of Steel and composite structures(concrete plus steel) of the National Roadway Network , without include seismic evaluation. The studies is based in the inventory and the inspections made by the Colombian Government’s Roads Institute (Invias) since 1996, throughout the Colombian Bridge Management System (Sipucol). This paper is divided in two parts: the first one presents a brief description of the different types of steel bridges and composite structures based on the Sipucol inventory module and the second one presents the state and typical damages of the main components. Of the 244 steel and composite structures bridges of the National Roadway Network, they presents structural deficiencies, widespread and partial corrosion, infiltration, not appropriate unions details, presence of fatigue problems in the unions and poor quality in welded unions. It is considered that this paper will be the base for a further and more comprehensive investigation of structures that are vital in the road infrastructure like the bridges, in order to advance in the detailed inspection including seismic vulnerability analysis, and conservation of steel bridges topics.
