Annotation:
The purpose of this work is to study the load-bearing capacity, deformability, and energy intensity of compressed reinforced concrete structures with spiral reinforcement. Experimental and theoretical studies have shown that the use of reinforced concrete structures with spiral reinforcement will significantly increase their deformability and energy intensity. This paper presents the results of an analysis of experimental studies of the stress-strain state of samples of 100x100x400 mm prisms made of concrete of classes B20 and B40 with spiral reinforcement with different pitches of turns and diameter of the reinforcement.
