Investigation of reinforced concrete columns with recessed longitudinal rods without transverse reinforcement

Abstract

The article deals with the feasibility of a significant increase in the thickness of the protective layer of longitudinal rods in compressed reinforced concrete columns. We describe the experimental data of the work of the reinforced concrete columns with recessed longitudinal reinforcement without transverse reinforcement. We provide a method for calculation of such structures and optimum parameters of the thickness of the protective layer on the criterion of maximum critical efforts.
