SPAN/LOADING NOTES. Deflection limited to L/360 live load & L/240 total load. Spans based upon a stair limits of 8 max rise and 9 min. run, governing building codes may be more restrictive. Contact National Lumber EWP Engineering for design. assistance on other stair stringer applications and/or loading.
The number of rises and actual rise is calculated to fit closest to selected ideal rise. After calculating and re-drawing stair plan diagram, a drop-down list of possible alternate rises is displayed. Select alternatives to re-calculate and display stair plan diagram. For notched stringers, mark out running measurements along stringer, then mark a framing square as shown (or attach Stair Gauges) to layout notch cut-outs. Or cut a template at the size shown and use to mark out notches along the stringer.
