Neste artigo descrevem-se os ensaios experimentais realizados e analisam-se os resultados obtidos com vigas de betão armado reforçadas com armaduras pós-instaladas de aço inoxidável com diferentes técnicas: Externally Bonded Reinforcement (EBR), Near Surface Mounted (NSM) e com o novo sistema de reforço desenvolvido - Continuous Reinforcement Embedded at Ends (CREatE). As vigas ensaiadas monotonicamente até à rotura em flexão de quatro pontos têm seção transversal em T e um vão livre de três metros. No novo sistema de reforço as armaduras são ancoradas por aderência no interior do elemento estrutural, o que associado à utilização de armaduras em aço inoxidável, possibilita aumentos de resistência e ductilidade consideráveis face às técnicas tradicionais de colagem pelo exterior.  &lt;/p&gt;
