Blast Loading in Existing Structures - Basement Models

Abstract

Experimental results are given for the effects of shock wave induced interior flows on small objects placed inside a 1/12th scale basement shelter. Pressure-time records and high speed photographs of the internal air flows created by exposure to outside shock overpressures of 5, 10 and 20 psi was presented. Flows down the inside stairway into the model were found to create a large scale circular motion around the room. Cross-the-floor components of velocity caused by these flows are given for the motion of the various objects placed inside the model.
