Shear Area Ay

Shear Area A_y

A_{y} = \frac{I_{z}^{2}}{\int_{A^{*}} {(\frac{S_{z}}{t^{*}})}^{2} d A^{*}}

I_z	Second moment of area related to the axis z
S_z	First moment of area in relation to the axis z
t*	Effective element thickness for the shear transfer
A*	Surface area based on the effective shear thickness t*
