FAILURE MODES OF IMPACT-LOADED FOOTINGS ON DENSE SAND. Technical Report R- 281
The design of foundation elements for protective structures which will resist the effects of nuclear weapons often requires predicting the response of a footing-soil system to impact or transient-type loads. This response has been, and continues to be, studied and reported by several governmental and institutional organizations who have recognized that the failure mode of the system is an important parameter in establishing a rational procedure to predict the response of a footing to an impact load. This report reviews the current (1 July 1963) literature, summarizes the various static and dynamic failure modes observed by several investigators, presents an analytical technique which explains the observed failure modes, suggests that the failure mode is dependent upon the footing acceleration during the impact loading, and defines the limiting footing accelerations associated with the two major failure modes.
