Cracking moment calculation does not consider axial load effects. #81

As per the title, no in-built method exists to calculate cracking moment under the presence of axial tension or compression forces. The assumption of the built-in calculate_cracking_moment() method is N*=0 kN

Under tension or compression, there is a direct tensile stress (and potentially a moment on the assumption of the axial load acting at the geometric centroid if section is non-symmetric) that is required to be combined with the moment component of stress.

Hi @Agent6-6-6, thanks for this. I meant to include this with the prestress module but clearly forgot to extend it to regular reinforced concrete sections as well! Will address shortly.
