Abstract

The main problem of reinforced flexible structures made of cellular concrete is a rather low specific adhesion at the border of the reinforcement with concrete. This negatively affects the pulling out of the reinforcement from the porous mass and leads to premature loss of the bearing capacity of the structure as a whole. The underestimation of the significant potential of the unused bearing capacity of the structure when using traditional reinforcement provides for the need to improve approaches to the reinforcement of flexible cellular concrete structures. Efficient reinforcement of cellular concrete structures is proposed to be carried out with reinforcing elements with a developed lateral surface - steel toothed belts, which significantly increase the contact area and qualitatively improve contact conditions. At the stage of computational justification, the results of an experimental study of the strength and deformability of samples of innovative reinforcing elements of steel toothed belts with various configurations of longitudinal perforation, which help to reduce the metal consumption of cellular concrete structures operating in bending, and directly improve their functional characteristics - thermal resistance and wave conductivity, are analyzed. The revealed variations in the physical and mechanical properties of reinforcement due to the changing pattern of its longitudinal perforation and the average characteristics of reinforcement used in the design analysis of reinforced cellular concrete structures are used to propose practical approaches to normalizing the values of characteristics and technologies for calculating reinforced cellular concrete structures
