Blast Loading on Above Ground Barricaded Munition Storage Magazines - 2
Abstract
This report presents results of a study designed to measure the blast loading on above ground munition storage magazines. The magazines are sited at separation distances of K2 (2W to the 1/3 power ft), K4 (4W to the 1/3 power ft) , and K6 (6W to the 1/3 power ft) where W is the maximum allowable high- explosive weight in pounds mass. Earth barricades protect the structures. Responding and nonresponding 1/23.5 scaled models were used for the test program. Loading results are presented for the nonresponding barricaded model magazine. The highest loading measured on the nonresponding model was on the side-wall nearest the donor magazine. Maximum values of reflected pressure at Station 3 were found to be about 900, 600 and 360 kPa for separation distances of 0.8 Q to the 1/3 power m, 1.6 Q to the 1/3 power m, and 2.4 Q to the 1/3 power m, respectively. Whole wall translation velocities calculated from the measured wall loading forces ranged from 7-12 m/s. These velocities are well under the fragment velocities needed to cause detonation of the stored munitions in the acceptor magazine. This indicated the present siting criteria of 0.8 Q to the 1/3 power m is safe for this type of above ground barricaded magazine. Additional costly greater siting distances should not be necessary.
