“…In construction practice, there are often situations when deformation is accompanied by a repulse of environment [10] and there is a problem of estimating the bearing capacity of a structure and reducing its damage level in the presence of such repulse under the influence of dynamic loads. A similar problem of dynamic loading of a multilayered pinched beam on a viscoelastic basis was considered in [11][12].…”

In this work, the problem of bending of a multilayered concrete beam of arbitrary cross-section by explosive loading on a visco-elastic basis is considered. It is assumed that different grades of concrete can be realized in layers in the cross-section. The property of concrete resistance to tension and compression is considered in work. It is assumed that the dynamic loading is caused by consecutive explosion of two charges over the middle of the span of beam. The distribution of bending moments and deflections of the beam at each time is determined. The time of the end of motion and the residual deflection of beam are found.
