Summary

This paper presents the results of an experimental program focused on the evaluation of the possibility of using a reduced scale in blast loading experiments. The blast wave propagation can be easily scaled using Hopkinson Scaling Law so it is possible to scale the loading applied to a specimen. However the behaviour of reduced scale reinforced concrete specimen remains questionable. Experimental results are supported with finite element calculations using the LS-DYNA software. Multiple methods of reinforcement modelling are proposed and discussed. The comparison of the finite element analysis with the results of the experiments brings a solid basis for understanding the behaviour of shock waves inside a specimen.
