Abstract
AbstractThe variation of pullout capacity of vertical strip anchor plates with width was studied while considering the effect of mean normal stress on the peak friction angle in a granular soil domain. This analysis was performed by using lower-bound finite-element limit analysis in conjunction with linear programing. The study was conducted for a wide range of anchor widths (B) and embedment depths (H) for both loose and dense sands. It was determined that the pullout capacity factor (Fγ = Pu/γBH) increases with decreasing values of normalized anchor width (γB/σA), where Pu is the ultimate pullout load; γ is the unit weight of soil mass; and σA is the atmospheric pressure. The rate of change for increments of Fγ with γB/σA was found to be more pronounced when the anchor is embedded in loose sand and at greater embedment depths.
