Lateral Pile Analysis (p-y)
Laterally loaded piles and drilled shafts by Broms ultimate capacity and nonlinear p-y finite-difference analysis — under lateral load and moment.
Start Free TrialWhat it does
The Lateral Pile tool analyzes single piles and drilled shafts under lateral load, shear, and applied moment. Choose Broms' closed-form ultimate-capacity method for a quick check, or run a full nonlinear p-y finite-difference solution for deflection, shear, and bending-moment profiles along the pile.
A complete p-y curve library covers soft and stiff clay (with and without free water), sand, silt, and weak rock, so you can model layered profiles the way the soil actually behaves. Automatic parameter tuning selects appropriate curve parameters from your soil inputs, with full override control.
Results include deflection, slope, moment, and shear distributions with depth, ground-line response, and the governing capacity — all in a formatted PDF calculation report.
