Benchmark solution
=====================

Calculation method used for the reference solution
--------------------------------------------------------

Average between the results obtained with different codes (8 results in [:ref:`bib1 <bib1>`]).


Benchmark results
----------------------

Critical load values for both load cases.


Uncertainty about the solution
---------------------------

The maximum deviation from the average of the results used is :math:`\text{2\%}`. This value is therefore associated with the uncertainty relating to the reference value.
