Eurocode 2 ULS design of I-shaped, T-shaped, and box-shaped reinforced concrete cross-section for bending and axial force
ULS design of I-shaped, T-shaped, and box-shaped reinforced concrete cross-section for bending and axial force (calculation of required reinforcement for given bending moment / axial force, maximum moment resistance MRd for given axial force, or complete M-N interaction diagram for given reinforcement layout)
EN 1992-1-1:2004+AC2:2010 Section 6.1
Uniaxial bending. Box-shaped cross-section can be treated as an equivalent I-shaped cross-section accounting for the total width of webs. Reinforcement layers of the flanges can be concentrated at the centerline of the corresponding flange as an approximation.
