註釋

The NCEL atomic blast simulator is intended for testing beams, beam- column connections, and other relatively narrow structural elements. This report describes the successful adaptation of the simulator for providing dynamic loads on a bearing plate on sand and presents some tentative results. The dynamic bearing capacity of a 15-in.-diameter bearing plate on dry sand without overburden was 90% higher than the static bearing capacity. Also, the dynamic bearing modulus was considerably higher than the static; e.g., 226 psi per in. dynamic versus 137.7 psi per in. static at 0.5 in. plate settlement.
