Identificação de manifestações patológicas no elemento estrutural pilar, no distrito de Amaniutuba, Lavras da Mangabeira - CE.

Abstract

Reinforced concrete elements are widely used in Brazilian civil construction. However, these elements, when used improperly, give rise to pathological manifestations. Thus, the present Course Conclusion Work aims to identify the pathological manifestations found in the pillar structural element. Twenty buildings were inspected in the district of Amaniutuba, in Lavras da Mangabeira - CE, with the help of NBR 16747/2020 and the GUT matrix, identifying priorities at levels of urgency. For this, the buildings were divided into two parts, those that have already presented pathologies and those that have not. It was found that all pillars were made of electrowelded metal trusses as frames. As for those that presented pathologies, one building with a fissure, one with a crack, three with cracks, four with concreting voids and three with pillars showing buckling were identified. The inspection carried out was confronted with the parameters required by NBR 6118/2014, concluding that the use of these trusses on pillars is in complete disagreement with the standard; the most incident pathological manifestations were concrete voids that are linked to the composition of the material and its execution; in conversations with those in charge of the buildings, it became evident that the choice of electrowelded metal trusses was for economic reasons, since using such a part costs less than 30% of the amount that would be spent compared to the parameters of NBR 6118/2014.
