Numerical study of a vertical pullout capacity of strip anchor plate on a frictional soil

This paper presents a numerical study of the ultimate pullout capacity of an isolated strip plate anchor, using the finite element method by Plaxis 2D software. The plate anchor is assumed rigid horizontally installed in a frictional soil and subjected to a centered vertical load. The soil behavior is governed by an elastic-perfectly plastic law, and Mohr-Coulomb criterion was adopted. The ultimate pullout capacity is expressed in terms of pullout factor N γ for different values of the depth H and the internal friction angle of soil φ' . The numerical results obtained allow us to propose a simple relationship to calculate the pullout factor of a strip plate anchor embedded horizontally in frictional soil. The numerical results of this study are finally compared to those available in the literature.
