Drilled shaft & caisson foundation designShaft3D
An integrated drilled shaft and caisson foundation design tool that combines axial capacity analysis, lateral load analysis, and reinforced concrete design in a single streamlined workflow. Applicable across transmission, transportation, residential, commercial, and industrial projects.
Fully Integrated Workflow: Axial analysis → Lateral analysis → Concrete design — all in one tool, with no need to switch between separate programs or re-enter data.
Complete Drilled Shaft Design in One Tool
Shaft3D integrates three critical analysis modules that are often handled by separate programs, saving time and reducing errors from data transfer.
Axial Capacity Analysis
Computes axial compression and tension capacity of drilled shafts using soil skin friction and end bearing, considering layered soil profiles.
Lateral Load Analysis
P-Y curve based lateral analysis for shafts under horizontal forces and moments. Computes deflections, rotations, shear, and moment along the shaft.
Concrete Section Design
Designs the reinforced concrete shaft section for combined axial load, bending moment, and shear — producing a complete structural design.
Layered Soil Profiles
Accepts multi-layer soil profiles with different properties for each layer, giving accurate capacity predictions in variable ground conditions.
Load Case Management
Handles multiple load cases and combinations for each shaft, streamlining analysis across all governing load scenarios.
Complete Design Documentation
Generates detailed output reports with all calculations, code checks, and reinforcement schedules for engineering review and submission.
Three-Module Design Process
01 — Axial Capacity
Skin friction and end bearing capacity from layered soil profile. Produces axial capacity vs. depth charts.
02 — Lateral Analysis
P-Y curve analysis for lateral loads and moments. Computes deflections and internal forces along shaft length.
03 — Concrete Design
Designs reinforced concrete section for combined axial, bending, and shear. Produces reinforcement schedule.
Applications by Sector
- Lattice tower shafts and mono-pole foundations (Transmission)
- Bridge pier and abutment foundations (Transportation)
- High-rise building caissons and low-rise piers (Commercial)
- Stack, flare, and vessel shaft foundations (Industrial)
Shaft3D includes DSAnchor integration for designing anchor bolts at the top of the shaft. Loads from the shaft analysis flow directly into DSAnchor.
