Anchor Bolt Capacity Calculator

Calculate tension, shear, and combined capacity of cast-in and post-installed anchors in concrete using ACI 318-19 Appendix D (now Chapter 17) concrete capacity design (CCD) method.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate tension, shear, and combined capacity of cast-in and post-installed anchors in concrete using ACI 318-19 Appendix D (now Chapter 17) concrete capacity design (CCD) method

Each component has a specific meaning:

  • ACI 318-19 Appendix D concrete capacity design method — The aci 318-19 appendix d concrete capacity design method recorded for the patient or scenario being assessed.

Note: Interpret the anchor bolt capacity result against the clinical thresholds and context described above.

How to Use

Enter the ACI 318-19 Appendix D concrete capacity design method for the patient or scenario you are assessing. Calculate tension, shear, and combined capacity of cast-in and post-installed anchors in concrete using ACI 318-19 Appendix D (now Chapter 17) concrete capacity design (CCD) method. Use the anchor bolt capacity result to inform your clinical assessment.
