Can I model sheet piles in STAAD.Pro ?
Sheet piles can be modeled using a mesh of plate elements. Assuming profiles would be corrugated and would have the same pattern repeated over the length, you can model one segment using a mesh of plates and then do a translational repeat ( Geometry > Translational Repeat ) to generate the full model. Any stiffeners to the walls can be modeled using beam elements. Fix the bottom of the sheet pile by applying FIXED supports to the plate nodes at the base. Hydrostatic load on plates can be used to model soil pressure or water pressure as needed.
