Innovative Av500P reinforcement rolling in the design of a reinforced concrete monolithic building

Abstract

Introduction. The use of new types of reinforcement is based on research and justification of the effectiveness of their use in the design and construction of real buildings and structures. Currently, the most commonly used type of reinforcement in the construction of buildings is A500C according to [1] GOST 34028–2016, which has a “sickle-shaped profile.” At the moment, the market has an innovative reinforcement profile, which, while maintaining the strength characteristics, provides better adhesion to concrete, this is a new four-row type of reinforcement Av500P with a two-way screw rolling profile according to [2] STO 36554501–068–2022. The new helical profile, according to [2], has a uniform distribution of wedging forces from the reinforcement surface, which results in better adhesion to concrete. The calculation of structures uses the recommendations of STO 36554501–068–2022 [2] for calculating the crack opening width of reinforced concrete foundation slabs and floor slabs.

The aim of this study is to identify the effectiveness of using Av500P reinforcement compared to A500C reinforcement. A 10-storey apartment building in Sochi was considered. Two calculations were performed to compare the metal consumption for the foundation slab and the floor.

Materials and methods. The project of a 10-storey apartment building in Sochi was considered. Two calculations were performed to compare the metal consumption for the foundation slab and the floor.

Results. When replacing A500C reinforcement with Av500P reinforcement in the foundation slab and ceiling, the consumption was lower.

Conclusions. The effectiveness of using the innovative Av500P reinforcement profile has been revealed in comparison with the conventional A500C reinforcement profile.
