TÉCNICAS DE REFORÇO ESTRUTURAL PARA EDIFICAÇÕES ANTIGAS. ESTUDO DE CASO NA CIDADE DE RIO BRANCO – ACRE

Abstract

This study aims to demonstrate the design and calculation verification based on NBR 6118 (ABNT, 2007) for reinforced concrete columns, focusing on structural reinforcement techniques for old buildings. Methods such as concrete jacketing, steel profiles, steel plate bonding, and carbon fiber-reinforced polymers (CFRP) were identified and analyzed. The case study of the revitalization of a historic building in Rio Branco - Acre demonstrated that the applied reinforcement technique increased the load-bearing capacity of the strengthened columns.
