Manifestações patológicas de elementos estruturais do viaduto entre as estações de trem de Ipiranga e Afogados - Recife–PE

Abstract

A pathological manifestation according to the NBR 15575 standard is any irregularity that occurs in the product (e.g. a residential building) and that occurs due to failures in the manufacturing, design, installation, assembly, execution, use or maintenance processes. These manifestations are not attributable to the natural aging of the product, but rather to problems that arise due to failures in the aforementioned processes. The objective of this work was to analyze and propose a corrective solution to the pathological manifestations in the reinforced concrete structure of a viaduct located on Rua Visconde de Pelotas in the neighborhood of Afogados, Recife-PE. An extensive visual inspection was carried out with a photographic collection. The structural elements were classified according to their type of coating, damage and aspects, in addition to the probable causes. The analysis of the level of deterioration was measured based on bibliographic references and current standards. From the diagnosis, organic matter, exposed reinforcement, loss of concrete cross-section and efflorescence are observed. Some corrective solutions for the pathologies found are suggested, such as cleaning the structure, removing organic matter, treating efflorescence and covering the exposed frame.
