PATOLOGIAS EM PONTES DE CONCRETO ARMADO COM APLICAÇÃO EM JUIZ DE FORA - MG

Abstract

Bridges play a crucial role in both architecture and the economy, serving as important elements of integration between regions. At the same time, they add architectural value to the locations where they are located. Special Works of Art, as bridges are known, constitute a valuable public heritage for the economic and social development of the nation. However, the conservation of these structures still requires greater attention and development. The lack of an effective maintenance routine can compromise their functioning, resulting in unnecessary expenses for repairs or even new constructions. Many bridges do not present the necessary information about their design and construction; the lack of cataloging is a critical factor, as is the lack of adequate maintenance records of the structures, including conservation data. In Brazil, reinforced concrete bridges are predominant, which makes it essential to evaluate the factors that can lead to the deterioration of these structures, in order to guarantee their safety and durability. The objective of this work is to identify the main pathologies in reinforced concrete bridges in Juiz de Fora, with the aim of pointing out such pathologies that affect the structures of the central bridges over the Paraibuna River. The methodology used in this study includes a visual inspection of reinforced concrete bridges in the central region of Juiz de Fora, especially those over the Paraibuna River, with photographic records of the pathologies identified. The evaluation of the lower part of the bridges was carried out according to accessibility.
