Avaliação de manifestações patológicas em estruturas de concreto armado através do método GDE/UnB

Abstract

The present work consists of applying the Degree of Deterioration of Elements (GDE/UnB) methodology in structural elements of reinforced concrete, focusing on pillars, beams and slabs of the first floor of the pilotis building in towers A and B. The methodology consists of carrying out a visual inspection at the case study location, assigning weights and grades according to the pathological manifestations found, to determine the degree of deterioration of each element individually. Then, the degree of deterioration of the family of elements is calculated, that is, of all the pillars, beams or slabs of the same tower, in order to assess the general quality of the structure. Finally, a degree of global damage is calculated to define the level of deterioration of the examined tower. The case study was carried out at the Sol Morar Building, located in Manaus, which has two towers, tower A and B with 12 and 24 apartments, respectively. Visual inspections were carried out to identify the pathological manifestations present in the structure, such as corrosion, cracks, carbonation, displacement and humidity. Based on the information obtained, the pathologies found were classified and appropriate solutions were proposed for each one of them, aiming to guarantee greater safety and durability of the structures. Based on the data collected, it is possible to conclude that there are a significant number of problems with pathological manifestations in the Sol Morar building, especially in the pillars of tower B. The proposed solutions involve specific repairs for each type of pathology identified, such as removal of degraded concrete, application of corrosion inhibitors and recomposition of concrete. In summary, the case study carried out at the Sol Morar Building using the GDE/UnB methodology allowed identifying, analyzing and classifying the main pathological manifestations present in the structure. The proposed solutions aim to improve the safety and durability of reinforced concrete structures, contributing to the understanding of these pathologies and providing guidelines for appropriate interventions.
