Explanations of the principal aspects of concrete destruction in the contact layer based on the basic provisions of the general theory of adhesion and anchoring of periodic profile reinforcement in concrete
Abstract
The theoretical substantiation of the change in the nature of concrete destruction of the contact layer in the anchoring zone depending on the geometric parameters of the periodic profile of the reinforcement in accordance with the basic provisions of the general theory of adhesion and anchoring of the reinforcement of the periodic profile in concrete (GTA) is presented. The analysis of the results of experimental studies confirming the change in the nature and sequence of concrete destruction in the anchoring zone when changing the pitch of the transverse ribs of the circular periodic profile of the form 1f according to GOST 34028–2016 “Reinforcing bars for reinforced concrete structures. Technical conditions” is made. The possibility of increasing the seismic resistance of reinforced concrete structures according to the GTA is proved when changing the geometric dimensions of the profile and the sequence of concrete destruction in the contact layer. The comparison of the properties of reinforcement with periodic profiles according to GOST 34028–2016 and reinforcement with a profile corresponding to the basic provisions of the GTA and the possibility of reducing the metal consumption of reinforced concrete due to including the transverse ribs of the profile in the stretching work is given.
