Equivalent Internal Forces of Polygonal Cross-section Walls (4.5.3.7 (d))

• For walls with rectangular cross-section shape, I, T, L, U or C, the resultant of the finite element node forces is automatically calculated as equivalent frame cross-section effects (bending / torsion moments, shear forces, axial force) at the cross-section gravity center, based on the reinforced concrete section calculation. obtained.

• The bending moment obtained in this way at the wall base is used as the curtain base overturning moment M _DEV in 4.3.4.5 , 4.3.4.6 and 4.3.4.7 .
