Reforço estrutural de uma edificação histórica na cidade de Rio Branco – Acre

Abstract

This work presents the application of structural reinforcement by jacketing with reinforced concrete in the revitalization of "Casarão", a historic building in Rio Branco (AC). The study focused on columns P21, P30, and P41, which exhibited insufficient resistance due to the use of concrete with brick aggregates and corrosion of reinforcements. The adopted technique ensured increased load-bearing capacity without significantly altering the original dimensions, preserving architectural features. The results demonstrated efficiency, meeting the requirements of NBR 6118 (ABNT, 2014).
