Abstract : The general purpose of this project was to obtain the necessary basic data from which to develop criteria for the economical and efficient design of underground protection from air-blast forces. The specific objectives were: (1) to investigate the nature of the forces transmitted from an air burst of an atomic device through the earth to underground structures; (2) to determine the variation of these forces with the depth of the structure in the earth and with the flexibility of the structural elements; and (3) to study the response of simple structural elements of different stiffnesses and effective masses subjected to the transmitted dynamic forces.
