AnchorPull Calc
iOS Universel / Utilitaires
AnchorPull Calc is a fast, offline concrete anchor capacity calculator for structural engineers, contractors, and inspectors. Determine pullout and shear strength of cast-in-place and post-installed anchors using the ACI 318 Concrete Capacity Design (CCD) method.
WHAT IT CALCULATES:
Tension (Pullout) Capacity:
- Concrete breakout strength per ACI 318 Chapter 17
- Projected failure area (ANc) with edge and spacing effects
- Modification factors for cracking, eccentricity, and lightweight concrete
- Basic breakout strength (Nb) based on embedment depth and concrete strength
Shear Capacity:
- Concrete breakout strength in shear
- Pryout strength for short, stiff anchors
- Edge distance effects on projected shear area (AVc)
- Modification factors for cracked concrete and load direction
Combined Loading:
- Tension-shear interaction check per ACI 318-19 Section 17.6
- Tri-linear and elliptical interaction curves
- Demand-to-capacity ratios for combined loading
ANCHOR TYPES SUPPORTED:
- Cast-in-place headed bolts and studs
- Post-installed expansion anchors
- Post-installed adhesive anchors
- Single anchors and anchor groups
KEY FEATURES:
- ACI 318-19 Chapter 17 compliant
- CCD method with all modification factors
- Edge distance and spacing warnings
- Cracked and uncracked concrete conditions
- Normal weight and lightweight concrete
- Works completely offline
- No account or login required
