Abstract : The behavior of foundations for protective structures is studies through a combination of theoretical and experimental research. Particular emphasis is placed on formulating a mathematical model which accurately predicts the gross motion of a dynamically loaded footing. A single-degree-of-freedom model incorporating a linear damping factor is developed and the results obtained from this model are correlated with the results from experiments performed under previous contracts. Other studies reported included three-dimensional static experiments of small model footings on cohesive soils; static experiments on a cohesionless soil where the footing and surrounding soil are subjected to overpressure; development of the logarithmic spiral failure surface for bearing capacity of continuous foundations; and a solution of a dissipation mechanism for dynamic soil behavior.
