Conclusions
The reaction of reinforced-concrete blast chambers to internal explosive loading has been investigated experimentally and numerically. The high resistance of the concrete within the reinforcing cage to shock-wave loading has been demonstrated, together with its substantial contribution to the load-carrying capacity of the chamber. It is noted that the disintegration of the chamber wall begins with the appearance of residual deformation of the inner shell. The loading of the chamber wall in the experiments is shown to be impulsive. A method of estimating the load-carrying capacity of chambers similar to those tested is proposed.
