OLIVEIRA, Dênio Ramam Carvalho de2025-03-132013https://rigalileo.itegam.org.br/handle/123456789/629This study aimed to demonstrate the design and verification of calculating the NBR 6118 (ABNT, 2007) with their geometric characteristics, encasing armor, armor, and buckling resistance of the compression pillars centered pillars of reinforced concrete, with the major bibliographic techniques for structural reinforcement of concrete columns for old buildings, identifying the main methodologies and techniques used in Brazil and presenting the strengths and weaknesses of each technique: concrete jacketing, steel profiles, steel plate glued, blanket / carbon cloth, aramid and glass and polymers reinforced with carbon fiber (CFRP). The results obtained by comparative analysis of reinforcement performed in the case study "revitalization of the old house" indicated that the reinforcement technique was studied efficient because all reinforced parts had a greater bearing capacity than the original pillar without strengthening.Reforço estruturalConcreto armadoFibras de carbonoFlexão compostaPilares retangularespdf.Engenharia Civil
