EXPERIMENTAL STUDIES OF DYNAMICALLY LOADED FOOTINGS ON SAND
Abstract
DENTIFIERS: Footings.An investigation of the strength and behavior of spread footings subjected to dynamic forces is reported. To this end a single-degree-of freedom model representing the spread footing and its supporting medium was developed. The supporting medium was restricted to either a cohesive or cohesionless soil. Tests were conducted to aid in the correlation of the model components with the anticipated response behavior of spread footings. A correlation between the analytical model and the experimental results could not justifiably be carried out as the container affected the test medium. Results showed a finite increase in the dynamic bearing capacity of spread footings over their static capacity. Within the limited instrumentation, the dynamic settlement of the test plates is due to the establishment of failure surfaces. For se tlements equal to the maximum dynamic settlement, the applied dynamic load varied from 1.20 to 2.28 times the equivalent static load. (Author)
