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:

• (1.0 – k₁)/k₂ * effective depth for f_ck ≤ 50 MPa
• (1.0 – k₃)/k₄ * effective depth for f_ck > 50 MPa

where k₁, k₂, k₃, and k₄ are taken from the National Annex.
