Title: Vertical uplift resistance of a group of two coaxial anchors in clay
Authors: Kumar J.

Published in: Journal of Geotechnical and Geoenvironmental Engineering
Abstract: The vertical uplift resistance for a group of two horizontal coaxial rigid strip anchors embedded in clay under undrained condition has been determined by using the upper bound theorem of limit analysis in combination with finite elements. An increase of undrained shear strength of soil mass with depth has been incorporated. The uplift factor F c? has been computed. As compared to a single isolated anchor, a group of two anchors provides greater magnitude of the uplift resistance. For a given embedment ratio, the group of two anchors generates almost the maximum uplift resistance when the upper anchor is located midway between ground surface and the lower anchor. For a given embedment ratio, increases linearly with an increase in the normalized unit weight of soil mass up to a certain value before attaining a certain maximum magnitude; the maximum value of F c? increases with an increase in embedment ratio. ¬© 2012 American Society of Civil Engineers.
