Innovative design of GFRP bars for Concrete Structures

[EN] This part analyzed GFRP rebar's research situation, summarized its behaviuor as internal reinforcement for concrete structures. The research has been developed over recent years, however the rules and standard codes for design RC concrete structures with these rebars not consider that the internal reinforcement can work in compression. This paper presents the development of the research to get a new kind GFRP rebar for work as internal reinforcement of concrete structures, with an innovative design for work both in tension and compression, and their mechanical properties: strength, bond,.... © (2012) Trans Tech Publications.Almerich Chulia, AI.; Martín Concepcion, PE.; Molines Cano, JM.; Rovira Soler, JA.
