Estudo de caso: reparo e reforço estrutural de um edifício residencial utilizando fibra de carbono

Abstract

This case study was conducted at the reinforced concrete residential building located in the city of São Paulo The selecton of this location was due to it being a large building, as it has 55 apartments and serving up to that number of families. Additionally, dispite being a new building, it presents relevant pathological problems, such as fissures, cracks in beams and crushing of pillars underground, which could result in the building falling into ruin. Thus, the aim of this work was to record the pathological manifestations present and, through a bibliographic review, identify the causes and the best solutions for the case. At the end of the study, as a participant observer together with the engineer responsible for the repair, it was found that the most efficient way (less invasive and destructive to the structure) in terms of saving materials, time and increased resistance using carbon fiber composites applied with epoxy resin. After reinforcement, monitoring was carried out to observe the behavior of the reinforced structure.
