Uplift Capacities of Triple-Plate Horizontal Circular Anchors in Sand

Abstract

Anchors have found varied applicability in the field of civil engineering; be it in foundations, in supporting diaphragm walls, to support waterfront structures, in bridge abutments, in supporting transmission towers. A variety of anchors have been experimented in small-scale model tests in the laboratory and tested in the field. Plate anchors, screw anchors, drag anchors, cement-grouted anchors, and shank anchors are a few to name. Researchers have studied, in both experimental studies, and analytical and numerical ones. The use of multi-plate anchors attached to the same tie rod has, however, been not yet considered. The authors present their idea of the use of multi-plate anchors here. The study describes the load–displacement behavior of both single-plate and triple-plate horizontal anchors of circular shape. The triple-plate anchors consist of three single-plate anchors attached to the same tie rod at a spacing (s) equal to the size of the anchor (d). The efficacy of additions of plates is checked by the detailed laboratory study, in the sand.
