1. Code basis

Aluminium Supporting Sheet

Code basis: EN 1999-1-4 screw shear resistance expression for aluminium/steel supporting members, with visible diameter and area checks.

2. Screw and action

Input Values

Warning: make sure the diameter entered is the correct effective screw diameter for this check. Confirm whether you are using threaded/root diameter or shank diameter from the manufacturer's datasheet.

4. Formula notes

Visible Method

  • Calculated area: As = πd2 / 4, with d in mm.
  • Shear resistance: Fv,Rd = 380 As / gamma M3 [N], with As in mm2.
  • This formula is shown as an aluminium-code screw check even though the screw is steel or stainless steel.
