“…In recent year's there was more research on the use of FRP reinforcement, as well as on vibrated concrete structures reinforced with longitudinal and transverse FRP reinforcement. Numerous articles [19,[22][23][24][25][26][27][28][29][30][31] have be published on the work of full circular cross section concentrically and eccentrically loaded concrete columns reinforced with FRP and GFRP and on the physical-mechanical properties of concrete. Our conclusions do not suggest an assessment of the influence of spiral reinforcement on the bearing capacity or deformability of annular cross section of centrifuged reinforced concrete structures.…”

This article explores the influence of transverse reinforcement (spiral) and high-strength longitudinal reinforcements on the physical-mechanical properties of centrifuged annular cross-section elements of concrete. The test results of almost 200 reinforced, and over 100 control elements are summarizing in this article. The longitudinal reinforcement ratio of samples produced in the laboratory and factory varied from 1.0% to 6.0%; the transverse reinforcement ratio varied from 0.25% to 1.25%; the pitch of spirals varied from 100 mm to 40 mm and the concrete strength varied from 25 MPa to 60 MPa. Experimental relationships of coefficients for concrete strength, moduli of elasticity and limits of the longitudinal strain of centrifuged concrete in reinforced concrete structures in short-term concentrically compression were proposed.
