Abstract
Pathological manifestations affect buildings in different aggressive environments. Thus, technical inspection actions and occasional interventions are necessary, using specific methodologies that can minimise subjectivity in this process and guarantee adequate solutions regarding durability. This research study applies inspection methodologies to a bridge located in northeastern Brazil. The researchers identified pathological manifestations and elements to be evaluated through the calculation of deterioration with an adapted version of the GDE method (assessment of the degree of structural deterioration), and also through a technical analysis of the DNIT standard. A “high” deterioration degree of 64.03 was obtained, as well as a technical grade of 3, characterising the structure as “potentially problematic”. Experience and technical qualification are crucial in these evaluations; however, the adapted GDE methodology has specificities that reduce subjectivity, enhancing the inspection process and setting the deadlines for eventual repairs. Hence, it was possible to quantify and classify the state of conservation of the structure, indicate the need for intervention and obtain comparisons between bridge inspection methods, ensuring the refinement of results and reproduction in other studies.
