How to Use This Calculator
- Enter Slab Thickness in inches, Concrete Unit Weight, and Shore Capacity per post.
- Enter Construction Live Load in psf (minimum 50 per ACI 347), Form Dead Load, and Bay Size.
- Review Total Design Load in psf and Max Shore Spacing to lay out the shoring grid.
- Check Practical Shore Spacing, Shore Utilization percentage, and Shores Per Bay.
- Use Bay Total Load in pounds to verify the capacity of stringers and joists spanning between shores.
