Cantilever Reinforcement

If the design fails in continuous shear at the cantilever, BC Calc® software can add a piece of plywood nailed to one side of the cantilever and re-run the analysis. If necessary, BC Calc will add plywood to the other side of the cantilever as well and run the analysis again. The Design report will note what was done.

The following rules apply to BCI cantilever reinforcement:

  • Reinforcement is allowed on one side only for double joists.
  • Reinforcement is not available for triple or quadruple joists.
  • Reinforced cantilevers must not exceed 2'-0".
  • Backspans for reinforced cantilevers must be at least 2'-0".
