Segmented = sum full-height piers; Perforated = Co reduction

Loads

Wind or seismic shear into this wall
Wall self + tributary roof dead, for overturning (0 = ignore)

Capacity (product ESR)

ASTM E72 / AC04 racking allowable from the product ESR
Panel-joint + plate connection allowable (ESR)
SIP shear-wall limit (confirm with ESR/PRS-610)
Optional - checks tension demand vs device (0 = skip)

This calculator is verified by 4 independent tests comparing its output against closed-form statics, NDS/SDPWS design-standard values and published worked examples. Full case-by-case results are in the PDF report.

Assumptions

  • OSB facings act as the in-plane shear web; allowable unit shear from the product ESR (full-scale ASTM E72 racking test).
  • Openings handled with the SDPWS segmented and perforated methods, as for wood shear walls.
  • Overturning about the critical pier toe; 0.6D resisting dead load.

Limitations

  • Allowable in-plane shear, spline/connection and hold-down values are PRODUCT-SPECIFIC - confirm with the panel ESR / PRS-610.
  • SIP aspect-ratio limit is an input (default 3.5) - verify per the ESR.
  • Rigid-base, single-story wall; no force-transfer-around-openings detailing check.

Results are for preliminary design and must be confirmed by a licensed engineer against the current adopted code and project-specific conditions.
