2.7.2 Design Internal Forces

Design Internal Forces

As described above, the calculation of stiffnesses is based on linear-elastic assumptions. The internal forces are transformed into the orthogonal reinforcement directions φ as well as to both surfaces s (top and bottom). The determined internal forces – bending moments mφ,s and axial forces nφ,s (torsion moments are eliminated by a transformation in the directions of reinforcement) – depend on the

  1. type of model,
  2. method of calculation,
  3. classification criterion.
