The Effect of Scaling Building Configuration Blast Experiments on Positive Phase Blast Wave Parameters

Explosions in an urban setting can have a significant negative impact. There is need to further understand the loading effects caused by blast’s interaction with structures. In conjunction this, of scaling and understanding limitations laboratory experiments are equally important given cost incurred for full-scale experiments. The aim this study was determine on blast wave parameters found reduced-scale scenario This paper presents results numerical modelling physical detonating cuboidal PE-4 charges measuring pressure direct line sight at three distinct positions around corner small-scale “building” parallel rear wall. Two scales were used, namely 75% 100%. Inter-scaling between 100% worked fairly well shielded Additionally, lab-scale compared similar (but not identical) field trials equivalent scale 250%. comparison idealised testing larger-scale published Gajewksi Sielicki 2020, indicated sensitivity factors such as detonator positioning, explosive material, charge confinement/mounting, building surface roughness, environment.
