Title of the articleMovement of the reinforcement of a periodic profile in the embedment under static load
Abstract.There is a need to develop a new method for calculating the displacement of the reinforcement of a periodic profile in the embedment under static loading, which most simply takes into account the actual work of the reinforcement and concrete in the zone of their direct contact, and also describes the stress-strain state at all stages of loading from the beginning of slippage to the destruction of the embedment. Objectives of the work: analysis of domestic and foreign studies and identification of the state of the issue in assessing the displacement of reinforcement in the embedment. A new model and a new method for calculating the displacement of reinforcement in concrete are proposed based on the analysis of existing models and methods for assessing the SSS. Results. Theoretical studies of the behavior of the reinforcement of a periodic profile in the embedment under static loading have been carried out. A new model of embedding operation is presented, on the basis of which the equations of reinforcement displacements are obtained, with the help of which it is possible to estimate the stress-strain state of the concrete-reinforcement contact at all stages of loading. Conclusions. The significance of the obtained results for the construction industry lies in the fact that the proposed model and calculation method allow the most accurate assessment of the stress-strain state of the "concrete-rebar" contact zone in the problem of drawing reinforcement of a periodic profile from a concrete block under static loading. This is a significant contribution to the theory of adhesion of ribbed reinforcement to concrete.
Keywords.reinforced concrete, reinforcement, periodic profile, adhesion, static loading, displacement.
