The development of the loading method was accomplished by a study of known theory and existing experimental data. Data obtained by shock tube studies were combined with theory to produce a set of fundamental parameter plots and a rational load-computation method. Equations of motion, used in the prediction of response, are discussed and possible alternate methods of solutions are given. (C.H.)

Wright-Patterson AFB, Ohio Primary Report No.: WTI-29 Note: Operation GREENHOUSE Journal Announcement: NSA16 Document Type: Report Language: English Results are reported in an investigation of the relationship of blast to structural-response damage. Methods for computing blast loading and response from basic blast data were developed and applied to the selected test structures to predict their behavior. Theoretical resuits are compared with test results to determine the validity of the analytical methods, the model relationships, and the magnitude and regimen of the several parameters. Instruments used in measuring the effects of blasts on the structures are described. Results of the tests indicate that the structures behaved as expected. It was concluded that pretest analytical methods are satisfactory, that there exists a definite scale relation of loading between small-scale models and prototypes, and that the basic parameters can be applied to other structures.
