How are internal forces and stresses of 2D elements considered and calculated in SCIA Engineer?
Conventions for the results on 2D members:
1. Basic magnitudes = Characteristic values
Bending (plates, shells)
· *Bending moments mx, my
· *Torsion moment mxy
· *Shear forces qx, qy (=vx, vy)
Membrane effects (walls, shells)
· *Membrane forces nx, ny
· *Shear force qxy (=nxy)
2. Principal magnitudes
3. Dimensional magnitudes = Design values
To derive the dimensional magnitudes from the basic magnitudes, formulas from the Eurocode are used.
