Abstract: The feasibility of predicting the dynamic response of nuclear blast loaded footings was investigated by applying the principles of similitude to small, square footings supported on the surface of a highly plastic, partially saturated clay. The model components were scaled from a hypothetical prototype assumed to consist of a lumped "structure mass" and spread footing resting on a cohesive soil and subjected to various nuclear airblast pulses. The model system was based on a gas-actuated dynamic loading machine which applied transient load pulses to 4-l/2-in.-, 6-in.-, and 8-in.-square plates supported by soil specimens of controlled shear strength. The model tests indicated distinct relations between peak dynamic live load and maximum footing displacement for the three footing sizes tested. When appropriate scale factors were applied, the results projected into a single load-displacement relation for the postulated prototype. Additional tests were conducted to investigate the influence of various parameters and boundary conditions present in the similitude study. NOTE: This file is large.
