Abstract : It is well known that strong blast waves are lethal for a living creature, while it is believed that weak blast waves are harmless. This might be the case when there is a head-on collision between an oncoming weak blast wave and the considered body; however, a completely different scenario takes place when the initially weak (safe) blast wave hits a body after multiple reflections from existing walls. Such cases take place when a weak blast wave, resulting from a sudden explosion, hits a residential complex. In the conducted experiment a very simple model of a three level building is subjected to a weak blast wave. The evolved wave pattern inside the building rooms is recorded by a sequence of schlieren photos and the prevailing pressures are deduced from numerical simulations.
