Internal calculations are performed in SI units.
These values are provided by the user; the tool does not determine code-based bolt capacities. Combined utilization uses the simplified elliptical interaction √(uV² + uT²).
The tool uses a linear rigid-plate model with identical bolt stiffness. It does not include member flexibility, contact mechanics, clearances, slip, friction, prying action, yielding, unequal preload, local bearing or the requirements of specific standards. Negative raw axial-distribution values indicate a compression region in the model, not an actual compressive bolt force.
