Estudo sobre manifestações patológicas em estruturas de concreto protendido: diagnóstico e prevenção

Abstract

The technologies developed for civil construction are being modernized over the years, bringing several benefits to consumers. In this sense, the prestressed concrete structures stand out, which is an advance in relation to reinforced concrete. In the prestressed elements, a previous state of tension is applied that improves its resistance and its behavior. However, this technology requires a specialized workforce for its use, since the incorrect use results in pathological manifestations, a sign that the prestressed element was damaged. In this way, the work, which was carried out through a bibliographic review, sought to find the most common pathological manifestations that occur in prestressed concrete structures, informing their respective origins, as well as their preventive actions. In addition, tests that can be performed on these structures are presented in order to obtain the origin of the problem. Thus, the importance of a specialized workforce in these structures was noted, since the correct execution of the technology together with preventive actions manages to prevent the structures from suffering from pathological manifestations and, with this, these structures act in a safe and durable way.
