(wx/wy) = (ly/lx)⁴

(wx/wy) = (ly/lx)

(wx/wy) = (ly/lx)²

Is equal to the depth of critical neutral axis; the concrete and steel attain their maximum stresses simultaneously

All listed here

Is less than the depth of critical neutral axis, the steel in the tensile zone attains its maximum stress earlier

Is greater than the depth of critical neutral axis, the concrete attains its maximum stress earlier

h = √(W/Aw) [(1 - sin φ)/(1 + sin φ)]²

h = (W/Aw) [(1 - sin φ)/(1 + sin φ)]²

h = (W/Aw) [(1 - sin φ)/(1 + sin φ)]

h = (W/Aw) [(1 + sin φ)/(1 + sin φ)]
