LEVEL TEXT Unclassified The air-blast loading on a three-dimensional model 950. ABSTRACT of a gabled shelter has been investigated in a shock tube in order to provide data which could be used to formulate design criteria for a blast-resistant structure. The loading was divided into two phases. Diffraction loading was recorded by means of piezo-electric gages located at various points on the surface of the model. The pressure-time records resulting from this instrumentation were supplemented by pressure distribution studies made by the interferometer method (two-dimensional). Drag loading was studied with a transient balance. The data obtained by the different methods were correlated and good agreement was found. The methods of applying shock tube data to field conditions are presented. With these methods, the piezo-gage pressure-time records are compared to records obtained in the field and show a good agreement. 10 references. 801.
