Full Scale Surface Blast Test for Steel Blast Cubicles
The purpose of thisstudy was to examine the load experienced by steel blast cubicles from a surface blast test at different standoff distances, and to verify the blast resistance capability of the blast cubicle observed in the test.Three identical blast cubicles with standoff distances of 6.1 m (20 ft), 7.6 m (25 ft), 9.1 m (30 ft) respectively were simultaneously subjected to a 23 kg (50 lb) TNT explosive.No permanent de formation was observed in the front and side walls of the blast cubicle after the blast test, except some out-of plane buckling of the roofs.The manual Structures to Resist the Effects of Accidental Explosions, Army TM 5-1300 conservatively predicted the blast pressure loadings obtained from the pressure transducers mounted on the cubicles.Data collected from accelerometers was compared to results from the analysis program SDOF and SAP2000.The cubicle walls exhibited elastic behavior without any visible permanent deformation.The wall facing the blast was found to experience the greatest loading and was the critical member.The roof, however, experienced substantial deformation.As the standoff distance from the blast increased, the pres sure loading experienced by the cubicles decreased.The cubicle closest to the blast was likely close to its limit.Thus, the structural design of the blast cubicle for the specified blast loads was efficient and economi cal without waste of construction material.
