Lateral Pile Response

Comprehensive concept tool using Broms-style ultimate lateral resistance and a simple stiffness-based deflection estimate. Use for prelim sizing only.

Geotechnical Engineering • #geotech Clay / Sand Free / Fixed head Short / Long pile

Scope note: For real design use p–y (layered soils), cyclic degradation, group effects, and a defensible EI (cracked/uncracked).

k is used for an indicative deflection estimate only.
