Among the WeStatiX results, the member stresses due to the internal forces are also presented.

Note that the stresses due to biaxial bending are calculated for sections with any shape, not necessarily symmetrical!

As a direct consequence, when calculating the normal stress due to bending at a point with coordinates \((y, z)\), it is necessary to consider the contribution of the moments acting in both directions.

The stress at a point belonging to the \(y\) axis is defined as follows:
