Seismic Pullout Capacity of Inclined Anchor Plates in Sand
Abstract By using the lower bound finite elements limit analysis, the pullout capacity of an inclined strip anchor plate embedded in a cohesionless soil medium has been computed with an inclusion of pseudo-static horizontal earthquake body forces. The variation of the pullout capacity factor (Fγ) with changes in horizontal earthquake acceleration co-efficient (αh) has been computed by varying the inclination angle (β) of the anchor plate between 0° and 90°. The results clearly reveal that the pullout capacity factor (Fγ) decreases significantly with an increase in the value of αh. The reduction in the pullout resistance due to seismic forces (1) becomes much more extensive for a vertical anchor plate as compared to the horizontal anchor, (2) decreases generally with increases in the soil friction angle (ϕ) and (3) increases with an increase in friction angle between soil and anchor plate (δ). The developments of the failure zone around the anchor plate were also examined by varying αh and β. The results obtained from the analysis compare well with the solutions reported in literature.
