Batter　piles　are　widely　used　in　geotechnical　engineering　when　substantial　lateral　resistance　is　needed　or　to　avoid　the　interference　with　existing　underground　constructions.　Nevertheless,　there　is　a　lack　of　fast　numerical　tools　for　nonlinear　soil-structure　interactions　problems　for　this　type　of　foundation.　A　novel　hypoplastic　macroelement　is　proposed,　able　to　reproduce　the　nonlinear　response　of　a　single　batter　pile　in　sand　under　monotonic　and　cyclic　static　loadings.　The　behavior　of　batter　piles　(15　degrees,　30　degrees,　and　45　degrees)　is　first　numerically　investigated　using　3D　finite　element　modeling　and　compared　with　the　behavior　of　vertical　piles.　It　is　shown　that　their　response　mainly　depends　on　the　pile　inclination　and　the　loading　direction.　Then,　starting　from　the　macroelement　for　single　vertical　piles　in　sand　by　Li　et　al　(Acta　Geotechnica,　11(2):373-390,　2016),　an　extension　is　proposed　to　take　into　account　the　pile　inclination　introducing　simple　analytical　equations　in　the　expression　describing　the　failure　surface.　3D　finite　element　numerical　models　are　adopted　to　validate　the　macroelement　that　is　proven　able　to　reproduce　the　nonlinear　behavior　in　terms　of　global　quantities　(forces-displacements)　and　to　significantly　reduce　the　necessary　computational　time.
