Strains and stresses in section I-I (uncracked)

$x \; \mathsf{ [m] }$

$q \; \mathsf{ [kN/m] }$

This app shows the deformations and corresponding internal forces (stress resultants) of a 10m long flexural beam.
The values are calculated assuming linear elastic concrete behaviour (serviceability).
However, the maximum values (e.g. M_Rd) were determined considering ultimate limit load.
