Reforço estrutural de pilares: análise e desenvolvimento em situação de estudo de caso

Abstract

Since the civil construction sector represents a social and economic milestone, both in Brazil and worldwide, which seeks to meet community demands, whether housing, industrial, infrastructure, etc., its constant rise has required an increase in the technical standards employed, that is, the uninterrupted development of the processes of improvement and elaboration of materials, equipment and constructive techniques. Among these criteria is the adoption of inputs with greater mechanical resistance, durability and better surface finishes, as in the case of reinforced concrete that replaced the former use of stones (BAUER, 1999). Despite being a material that is best used on the construction site, reinforced concrete, as well as other civil construction materials, has limitations in terms of durability and performance that cause the appearance of structural pathologies over time. In this way, it appears that any and all buildings, however satisfactorily designed and executed, will present over the years some manifestation of structural deterioration and consequently some pathology of a structural nature. Faced with this situation, a new sector of technical development in civil engineering called structural reinforcement appears, which seeks to discuss analytical behavior and structural problems in a scientific and technical way. This new topic seeks to understand the origins, manifestation, mechanisms and systems of structural degradation (SOUZA; RIPPER, 2009). In this way, the present work seeks to present, in a succinct way, the causes and constructive techniques of structural reinforcement applied in a situation in a case study of reinforced concrete elements in centered compression (pillars), as well as the stages of analysis, development and elaboration of structural recovery projects.
