Pullout behavior of vertical ground anchor in dry homogeneous sand at different relative densities / Mohd Rafe Abdul Majid and Ideris Zakaria

Vertical ground anchors are commonly used in foundation systems for structures requiring pullout resistance such as transmission towers, structures requiring lateral resistance, such as sheet pile walls. The work described in this research is primarily concerned with the pullout capacity of a vertic...
