DeepFND is a powerful, user-friendly software tool for deep foundation pile design that brings together geotechnical and structural calculations in one integrated environment. It allows engineers to compute axial geotechnical pile capacity (skin friction, end bearing) and estimate settlement response from SPT or CPT inputs, perform full lateral pile analysis (displacement, shear, moment) via defined head-loads or pushover routines, and design single piles, pile groups, and pile rafts, including custom pile-cap geometries. It supports nearly all pile types, drilled, driven, CFA, caissons, drilled-in-displacement, micropiles, and helical piles, and models soil-structure interaction either via soil springs or a full 3D finite-element engine. It enables structural checks under service and factored load conditions using international design codes (ACI, AISC, Eurocodes, AS/NZS, Chinese Standards, AASHTO LRFD).
