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.

钢筋混凝土结构中离心混凝土的力学性能。

本文探讨了横向钢筋（螺旋形）和高强度纵向钢筋对离心环形截面混凝土构件的物理机械性能的影响。本文总结了将近200个钢筋和100多个控制元件的测试结果。实验室和工厂生产的样品的纵向增强率从1.0％到6.0％不等；横向加固率从0.25％到1.25％不等。螺旋的螺距从100 mm到40 mm不等，混凝土强度从25 MPa到60 MPa不等。提出了钢筋混凝土结构短期同心受压时混凝土强度系数，弹性模量和离心混凝土纵向应变极限的试验关系。
