Dynamic Bearing Capacity of Soils. Investigation of a Dimensionless Load-Displacement Relation for Footings on Clay

Abstract

Three nondimensional relations developed to predict the maximum displacement and the time of its occurrence for dynamically loaded square footings on clay were presented in Dynamic Bearing Capacity of Soils, Report 3. Additional tests reported herein were conducted which verified these relations and showed them to be independent of the model scaling rules used to design the footing tests in which they were first observed. The first relation is that of resistance parameter versus displacement parameter where the resistance parameter is the ratio of the average stress on the footing at maximum dynamic footing load to the static unconsolidated, undrained shear strength and the displacement parameter is the ratio of maximum footing displacement to footing width. The second is that of strength parameter to displacement parameter where the strength parameter is the ratio of maximum dynamic column load to the product of footing area and shear strength. The third relation is that of strength parameter to inertia parameter where the inertia parameter is the ratio of the product of maximum column load and the square of the time to maximum displacement to to the product of footing width and load column mass.
