GeoStructural Analysis foundation design modules enable users to quickly and easily develop sophisticated scenarios to facilitate designing, testing, and optimizing different foundations.
Piles
 Design for single-pile load displacement performance, considering combined vertical, horizontal, and moment loading.
Key Features
- Compute pile load-displacement curves through modeling the soil load deformation response as equivalent springs
- Output calculations, including bending moment, enable the structural design of the pile
- Model tapered piles through changing pile diameter as a function of depth
- Accommodate influence of installation method on pile performance
- Apply various pile cross-section shapes, including rectangle, circle (pipe), and H cross-sections
- Apply downdrag (negative skin friction) forces to model residual driving stresses or soil settlement
- Accurately model pile material, including steel, reinforced concrete, timber, and composite
- Check reinforced concrete cross-section design against a variety of industry design codes
- Determine the modulus of subsoil reaction around the pile against your own input or a variety of theories (Vesic, Mattlock and Rees, Ménard, Schmitt, and Chadeisson)
Pile CPT
 Utilize CPT data obtained at project sites to directly design pile foundations.
- Direct input of CPT data from gINT and other data formats
- Define ground water table conditions and soil stratigraphy using embedded soil database or project specific soil information
- Compute load-displacement curve
- Specify pile shape (e.g., circular, rectangular) and material type (e.g., concrete, steel, timber)
- Consider method of installation, including driven, vibrated, or cast-in-place
- Perform design for single pile and for pile groups
- Consider downdrag (negative skin friction) forces
- Implement CPT based pile design methods developed by LCPC (Bustamante), Schmertmann, Eurocode 7-2 (EN 1997-3), and NEN 6743 (Netherlands standard)
Micropiles
 Design, analyze, and evaluate micropiles subjected to axial and moment loading.
- Specify geometry of unbonded (free-section) and bonded ("root") micropile sections as well as micropile inclination
- Specify cement and steel properties of micropile
- Define groundwater conditions in the subsurface
- Define loading conditions of micropile, including tension and compression axial loads as well as moment loads
- Evaluate stability against buckling failure using theories developed by Salas and by Souch as well as the fundamental solution for buckling of a prismatic beam
- Evaluate stability of micropile cross-section design over the estimated project lifetime
- Analyze capacity of the bonded ("root") section using the methods developed by Lizzi, Littlejohn, Zwek, Bowlese, and Veas
Spread Footing
 Optimize spread footing designs that are subject to vertical, horizontal and moment loading. Design based on a range of criteria, including bearing capacity as well as settlement and rotation. It also determines the longitudinal and shear reinforcement required within the footing for structural stability. Design and analyze retaining walls in a variety of shapes and with anchoring.
- Select from a variety of spread footings, including circular, rectangular, strip footing, stepped, centric, eccentric, etc.
- Apply an unlimited number of surcharge loads to spread footings of varying configurations, including trapezoidal, strip, and concentrated load distributions
- Model water conditions beneath the spread footing, including artesian water conditions
- Model spread footing supported on replaced and compacted sand/gravel fill
- Specify surface terrain and subsurface stratigraphy
- Accommodates inclined footing base and sloping ground surface
- Evaluate spread footing bearing capacity against a variety of accepted methods such as Brinch-Hansen
- Predict settlement analyses and footing rotation based on methods such as Janbu, Buisman, and Soft Soil
- Estimate secondary settlement according to Lade
- Analyze foundations supported on soil under drained or undrained conditions or on rock
- Accommodate influence of combined bending and tension/compression on the shape of the stress diagram under the footing
- Determine the longitudinal and shear reinforcement required within the footing for structural stability
