Section 5.5 Redistribution of moments (Ductility Check)
Included code sections – (4)
Excluded code sections – (1), (2), (3), (5), (6)
RAM Concept does not currently redistribute moments, but applies 5.5(4) as a limit to the neutral axis depth, thereby ensuring ductility.
The neutral axis depth is limited to:
where k1, k2, k3, and k4 are taken from the National Annex.
