2.7.10.3 Selection of internal design forces

Selection of internal design forces

First, the internal forces are transformed in the first reinforcement direction φ1. The bending moments have different values for the bottom (+z) and the top (-z) surface; the axial forces have the same algebraic signs after the transformation.

mϕ1,+z = -30 kNmϕ1,-z = 30 kNnϕ1,+z = nϕ1,-z = -100 kN
