Identificación y análisis de patologías en puentes de carreteras urbanas y rurales

Abstract

A concern with a great number of bridges with significant pathological problems was the motivating factor to carry out this research. Small and medium size bridges have significant relevance for the economic and social development of the country, because they must ensure the transit of people, vehicles with raw material and local produce. However, the precarious conditions of bridges in the urban and rural areas make the displacement difficult, causing discomfort and unsafety for users. Furthermore, the transportation costs for producers and the maintenance for the local government continue to increase. This article intends to show the conservation conditions of small and medium sized bridges in the urban and rural region of Campinas (SP)-Brazil. Thus, this study is based on the analysis of four bridges of this region, in which is presented several examples in situ of the pathological manifestations in concrete, steel and wood bridges. This article also focuses on the design of bridges and its relationship with the pathological condition establishing concepts that could be applied to the corrective method and the pathology identification in concrete, steel and wood bridges. Finally, it aims to conclude that the most appropriate way to avoid a pathological state is preventive maintenance.

The influence of the use of regulatory codes on the diagnosis of pathologies of reinforced concrete frame bridges

“…Research on bridge pathologies requires significant resources in the form of machinery and experienced bridge inspectors who assess the condition of bridges on site (Catbas & Avci, 2022) and methods for digital transformation of bridge inspection, monitoring and maintenance processes (Bittencourt et al, 2021). Mascia and Sartorti (2011) studied bridge design and its relationship to pathological method and identification of pathologies in concrete, steel and wood bridges. Evaluations of bridge performance indicators have been proposed and implemented in case studies such as Marić et al (2022), Mahdi et al (2022) and Limongelli et al (2018) and many European directives on the quantification of performance indicators to assess bridge quality control have been issued (Santos et al, 2022).…”

Identification and analysis of pathological defect appearance in superstructures of reinforced-concrete bridges in Chapare region, Bolivia

“…Bridges are important structures for economic and social development of communities and become the civil infrastructure of a country to support communication between points including any kind of barriers [1]. There are many design criteria for these structures in order to obtain safety, reliability and durability.…”

Inspección De Puentes De Hormigón Armado Con Termografía Infrarroja: Estudio De Caso

“…Los puentes se caracterizan por ser estructuras importantes para el desarrollo económico y relacionamiento entre comunidades; no obstante, estas estructuras son propensas a desarrollar diversos problemas (Mascia and Sartorti, 2011). En Bolivia, un estudio realizado en el tramo Cochabamba -Santa Cruz, reveló que, de 35 puentes, 20 tienen severas observaciones (El Deber, 2015) y se reporta constantemente el colapso de estas estructuras, la mayoría localizadas en la región de Cochabamba (La Opinión, 2015), demostrando la ineficiencia de las entidades encargadas y la falta de programas periódicos de inspección y mantenimiento.…”
