The loading problem is to predict the forces imposed on an isolated
structure which is struck by a given blast wave moving across the structure
in a direction normal to one of its faces, and the net horizontal and
vertical forces as function of time are found for the period during which
the structure is immersed in the wave. 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.)

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.
