tnxFoundation is a standalone application for tower foundation design. It may be used as an extension of tnxTower, or as a separate program. tnxFoundation features automatic import of support geometry and load data from tnxTower analyses. Alternatively, this information can be entered manually for each foundation design project.

• Multiple foundation types (Pad and Pier, Pad, Caisson, Pad with Piles, Pad and Pier with Piles, Mat and Piers, Mat, Mat with Piles, Mat and Piers with Piles)
• Material and geometry type definitions
• Soil layer definitions
• Imported or user-defined load cases and load combinations
• Foundation geometry optimization
• Foundation stability verification
• Required reinforcement determination
• Post-installed anchor analysis
• Reports with calculation results
• Import of tower support data (monopoles, self-supporting lattice towers, guyed towers, guy anchor blocks)
• Supported unit systems: US and Metric
• User-editable databases (concrete, reinforcing steel, steel pile, soils)

• Complete verification of failure modes: bearing, sliding, uplift, and overturning
• Concrete footing analysis and design: flexure, one-way and punching shear, geometry optimization
• Concrete caisson analysis and design: flexure, compression, uplift, lateral loads (Broms, p-y), geometry optimization
• Pile and pile cap analysis and design: single pile and pile group compression/tension, pile axial capacity, pile cap flexure, one-way and punching shear, geometry optimization
• tnxFoundation caisson diagrams 

• Geotechnical and structural design reports
• Summary and detailed reports for all foundation types
• Shear, moment, and deflection diagrams for caissons
• Clear and comprehensive presentation of the results
• MS Word and PDF formatted documents
