Practical Recommendations

The process of propagation of a wave packet in the concrete mixture during the formation of reinforced concrete products by harmonic and shock-vibrational actions was considered. It was shown that the displacement of the layers of the concrete mixture during the propagation of the shock wave is directed against the direction of wave propagation, providing a sealing effect. On the basis of experimental studies, practical recommendations are given for determining the rational thickness of the compacted concrete mixture, depending on the frequency of oscillations.

AbstractThe paper deals with numerical simulations of wave propagation in reinforced concrete for damage detection purposes. A novel formulation of a 3D spectral element was proposed. The reinforcement modelled as the truss spectral element was embedded in the 3D solid spectral finite element. Numerical simulations have been conducted on cuboid concrete specimens reinforced with two steel bars. Different degradation models were considered to study the real behaviour of bended beams.
