What This Screw Shear Calculator Helps Check
The screw shear calculator supports focused review of a screw loaded in shear within an aluminium connection. It is intended for quick engineering checks where screw diameter, applied shear force, and design resistance need to be assessed before carrying the result into a wider connection design.
Typical Inputs
Common inputs include the applied shear force, screw diameter, number of screws where relevant, selected resistance basis, and the partial factor used by the aluminium connection workflow.
EN 1999 Aluminium Connection Context
Aluminium screw shear checks are normally reviewed as part of an EN 1999 connection workflow. The result should be considered alongside screw tension, screw pull-out, bearing, spacing, edge distance, local sheet behaviour, and project-specific fabrication requirements.
Diameter-Derived Shear Area
The tool uses screw diameter to derive the shear area used in the check. The selected diameter should match the fastener used in the physical connection detail and project specification.
Result Review
The engineering tool reports resistance, utilization, and pass/fail status so the aluminium screw shear check can be reviewed clearly. The output is for preliminary engineering review and should not replace a full connection design by a qualified engineer.
Practical Use
Use this check when reviewing EN 1999 aluminium screw shear resistance, screw shear capacity, or a quick shear check for fasteners in aluminium members or sheets.
Frequently Asked Questions
What is screw shear in an aluminium connection?
Screw shear checks whether the screw has enough resistance for a force acting across the fastener section in an aluminium connection.
What inputs are usually needed for aluminium screw shear?
Typical inputs include applied shear force, screw diameter, number of fasteners where relevant, and the resistance factors used by the design basis.
Is screw shear the same as screw pull-out?
No. Screw shear checks force across the screw section, while screw pull-out checks withdrawal resistance from the supporting aluminium material.
Is screw shear the only check needed?
No. Screw tension, pull-out, bearing, spacing, edge distance, local sheet resistance, combined actions, and project detailing may also need to be reviewed.
