Simulation of the interaction of concrete and reinforcement in the problem of simple tension

Аннотация

A simple dependence of the forces applied to the reinforcing bar on its displacement in the process of pulling the rod out of the concrete block is proposed. The basis for the shape of the curve and its characteristic points are taken known experimental data. Equations are written to obtain the coefficients of the curve. The corresponding curve is compared with similar, obtained according to known criteria. The advantages of the proposed description of the phenomenon are noted.
