Inclined Pullout Capacity of Plate Anchors in Sand
Keywords:
Plate Anchor, Limit Analysis, Inclined Pullout CapacityAbstract
This paper presents a numerical solution of the inclined pullout capacity of plate anchors in sand. The two dimensional plane strain finite element limit analysis was employed to determine the stability of this problem. A plate anchor with a width (B) and an embedded depth (H) is loaded by an inclined force (P) with an angle from the vertical. For finite element limit analysis, the sand is modelled as the volume element with Mohr-Coulomb material in a drained condition where the parameters are unit weight (
) and friction angle (). The plate anchor is modelled as the plate element with the elastic material. Parametric studies were performed for three dimensionless variables including embedment ratio (H/B), friction angle (), and load inclination (
). Results were summarized in the form of the dimensionless inclined pullout capacity (P/
HB) as a function of those input variables.
