The paper describes the air blast effect of a confined explosion of 5 ton TNT stored in a specially designed storage magazine of size 3.6 m X 4.5 m X 3.6m. Brick masonry targets of size 3m X 3m X 3m were constructed at various quantity distances ranging from 2.4 Q ~(1/3) to 22 Q~(1/3) and in varying orientation around the test magazine. Q is the quantity of charge in kg of TNT. Extensive blast and ground shock instrumentation was deployed around the target structures to monitor the air blast and ground shock effects in the vicinity of these structure. The paper discusses the blast structure interaction and the determination of key blast parameters that result in damage. The acquired data was used for developing quantitative correlations for determining the safety distances for brick masonry buildings.
