INVESTIGATION INTO THE EFFECTIVENESS OF A COLUMN CONFINEMENT WITH TEXTILE REINFORCED CONCRETE (TRC)

This paper aims to analyze the results of uniaxial compression tests conducted on textile-reinforced concrete (TRC) – confined reinforced concrete (RC) columns. The aim of this study is the investigation of various influences on the achievable strengthening effect. The impact of the ratio of textile reinforcement and concrete strength on ultimate strength increase is evaluated. Also, the influence of the concrete jacket on the overall increase in load-bearing capacity was investigated. The results show an increase in strength and deformation related to the unstrengthened reference columns. Also, a higher ductility of the reinforced columns could be achieved.
