Bolt Bearing in Steel Calculator

Use VitraLab to review local bolt bearing resistance in steel connection checks, then open the focused engineering tool for calculation input.

What This Bolt Bearing in Steel Calculator Helps Check

The bolt bearing in steel calculator supports focused review of local bearing resistance where a bolt bears against a steel plate or connected member. It is intended for quick engineering checks where hole geometry, plate thickness, material strength, and bolt position need to be assessed before carrying the result into a wider connection design.

Typical Inputs

Common inputs include the applied bearing force, bolt diameter, hole diameter, plate thickness, steel material strength, end distance, edge distance, and whether the check is for a single bolt or an edge condition.

EN 1993 Steel Connection Context

Steel bolt bearing checks are normally reviewed as part of an EN 1993 connection design workflow. The result should be considered alongside bolt shear, bolt tension, spacing, edge distance, plate resistance, net section, block tearing, and any combined-action checks required by the project.

Hole Geometry and Bolt Position

Bearing resistance can change with hole size, end distance, edge distance, slotted holes, and the actual bolt position in the joint. The selected inputs should match the physical connection detail and drawing dimensions.

Result Review

The engineering tool reports resistance, utilization, warnings, and pass/fail status so the steel bearing check can be reviewed clearly. The output is for preliminary engineering review and should not replace a full connection design by a qualified engineer.

Steel and Aluminium Difference

Bolt bearing in steel and bolt bearing in aluminium may look similar as a connection check, but the design basis is different. Steel bearing is reviewed with EN 1993 assumptions, while aluminium bearing is reviewed with EN 1999 assumptions.

Frequently Asked Questions

What is a bolt bearing check in steel?

A bolt bearing check in steel reviews whether the steel material around a bolt hole has enough local bearing resistance for the applied force.

What inputs are usually needed for steel bolt bearing resistance?

Typical inputs include bolt diameter, hole diameter, applied force, plate thickness, steel material strength, end distance, edge distance, and the relevant connection condition.

Is bolt bearing the same as bolt shear?

No. Bolt bearing checks the local resistance of the connected material around the hole, while bolt shear checks the shear resistance of the bolt itself.

Is steel bolt bearing checked the same way as aluminium bolt bearing?

No. The engineering idea is similar, but steel bearing is normally reviewed with EN 1993 assumptions, while aluminium bearing is reviewed with EN 1999 assumptions.
