Juliane da Costa Santos,Ana Caroline da Costa Santos,Paul Archbold,Rogério Francisco Küster Puppi +3 more
TL;DR: In this article, an experimental analysis about the monotonic flexural behaviour and ultimate capacity of 10 reinforced concrete beams partially damaged and cracked after preloading in flexure was presented. And the effectiveness of the carbon fiber reinforced polymer (CFRP) when used as an external strengthening to recover the damaged structures of reinforced concrete studied, submitted to their ultimate flexural tensile load.
