  1. * Effective depth.
  2. ** Longitudinal reinforcement ratio \(\frac{A_{sl}}{b_{w}d}\) with \(A_{sl}\) area of longitudinal reinforcement and \(b_{w}\) web width.
  3. *** Shear reinforcement ratio \(\rho _{w}=\frac{A_{sw}}{b_{w}s}\) with \(\frac{A_{sw}}{s}\) the area of shear reinforcement per unit length.
