Abstract

"The dynamic pullout resistance of anchors was investigated through the use of model testing under controlled conditions. The soil used for the model tests was a dry sand compacted to a uniform relative density of approximately 92 percent. The dynamic loading of the anchor-soil system was applied by a mechanical device, which applied a specific amplitude and frequency of dynamic load to the anchor-soil system.

The dynamic testing of the anchors consisted of two phases. First, an initial static load was applied to the anchor. Second, a dynamic load was superimposed over the initial static load. The load applied to the anchor and the anchors' deflection was monitored throughout the test. The anchor-soil system was also tested under static loading conditions. In these static tests the load on the anchor-soil system was gradually increased until the ultimate capacity of the anchor-soil system was reached.

An analysis of the resulting tests indicated that for a given frequency and amplitude of dynamic load, the ultimate load resisted by the anchor-soil system in the dynamic tests was greater than the ultimate load resisted by the anchor-soil system in the static tests. It was also found that the magnitude of dynamic load resisted by the anchor-soil system was dependent on the initial static load applied to the anchor"-- Abstract, p. ii
