XConstruct provides a concrete module with an integrated M-N-kappa diagram. For all types of concrete cross-sections. It is also integrated into XBeam2D. As a result, the deflection calculation in XBeam2D is Physically Non-Linear. The modulus of elasticity belonging to the bending moment at a certain location in the cross-section is calculated and used for the force distribution and deflection calculation.
Also, all entered formulas can be seen in the output making the calculation fully transparent.
