“…Design standards are being prepared in Brazil and Uruguay. The successful experience of using composite reinforcement in compressed and compressed-bendable elements [11][12][13][14][15] determines its further use in structures operated in aggressive environments. Nevertheless, the use of composite reinforcement is still constrained by the lack of calculation methods and examples.…”

The article presents the results of the computational analysis of compressed concrete columns of a water tank with GFRP reinforcement. It is analytically proved that with an increase in the confinement reinforcement ratio and the magnitude of the relative lateral pressure coefficient due to an increase in the congestion of the longitudinal and transverse reinforcement, the strength of the effectively compressed core increases linearly. The strength of the effectively confined concrete core in GFRP reinforced specimens is somewhat less compared to similar specimens reinforced with steel reinforcement. The coefficient of strengthening of columns (in relation to a pure concrete specimen without reinforcement) increases with increasing frequency of transverse reinforcement. At the same time, the calculated strength of columns with GFRP reinforcement is only 10% less than that of similar columns with steel reinforcement.
