Abstract

Infrared thermography represents the possibility of making graphic records of the temperature of objects that are most varied. Icons of modern and monumental architecture, as well as the use of reinforced concrete in Brazil, several buildings in Brasilia are already more than fifty years old and present different pathological manifestations. This paper presents a study of the application of infrared thermography for the identification of pathologies and the state of conservation in the reinforced concrete elements of the Raymundo Faoro Palace of Justice. From the thermographic records, it was possible to evaluate the thermal behavior of several pathologies and to compare them with previous studies that did not use this technique. In this study infrared thermography proved useful as an aid capable of providing information for the maintenance and conservation of the building, showing the thermal behavior of structural elements, the positioning of pathologies in relation to hidden structural elements, the presence of infiltrations, spots and the thermal gradients capable of compromising the structure.
