Anchorage-to-concrete designDSAnchor
DSAnchor streamlines the process of designing anchors for concrete foundations using an intuitive graphical interface. It helps engineers determine safe anchorage for equipment and structures quickly and accurately — and is fully integrated into Foundation3D, Mat3D, and Shaft3D.
DSAnchor is integrated into Foundation3D, Mat3D, and Shaft3D — enter load cases once and design anchorage without re-entering data.
Comprehensive Anchor Database
DSAnchor supports all common anchor types used in industrial and structural engineering, from cast-in-place bolts to post-installed bonded systems.
Cast-in Headed Bolts
Standard cast-in-place anchor bolts with head bearing.
Headed Studs
Welded headed studs for embedded plate connections.
Hooked Bolts
J-bolt and L-bolt configurations for cast-in applications.
Mechanical Anchors
Post-installed expansion and undercut anchor systems.
Bonded Anchors
Adhesive and grouted post-installed anchor systems.
All ACI 318 Failure Modes Covered
DSAnchor checks every applicable failure mode defined in ACI 318 for both tension and shear loading. Governing and non-governing modes are clearly identified in the output.
- Steel failure in tension
- Concrete breakout in tension
- Pullout / pull-through failure
- Concrete side-face blowout
- Concrete splitting failure
- Steel failure in shear
- Concrete breakout in shear
- Concrete pryout failure
Key Features
Rectangular & Circular Patterns
Supports both rectangular and circular anchor patterns, including symmetrical and asymmetrical configurations for non-standard equipment.
Single & Group Anchor Analysis
Calculates forces and capacities for individual anchors and anchor groups, accounting for group effects per ACI 318.
Axial & Biaxial Bending Loads
Handles anchor groups under combined axial loads and biaxial bending moments — the real-world loading condition for most equipment.
Parameter Override
All default parameters can be overridden, giving engineers full control over design assumptions and material properties.
Graphical Failure Mode Visualization
Visual representation of governing and non-governing failure modes to aid engineering judgment and peer review.
Tension & Shear Recommendations
Provides clear pass/fail status and capacity utilization ratios for both tension and shear load combinations.
Development Length Calculations
Integrated development length checks for anchor bolt extensions into concrete elements per applicable code provisions.
Detailed Reports with Code References
Comprehensive output reports showing all equations, intermediate values, and ACI 318 code clause references.
Seamless Integration
Because DSAnchor is embedded directly inside Foundation3D, Mat3D, and Shaft3D, engineers can move from foundation design to anchor design without switching applications or re-entering any load data.
