# What does note 40162 show regarding the shear strengths of Binderholz?

For the structures of the manufacturer Binderholz, the shear strengths are calculated according to the following equation as soon as the plates without thin-edge gluing have been defined and are calculated with a design of the shear failure in the plane of the pane.

$f_{v,k}=\left\{\begin{array}{l}\begin{array}{c}3,5\\8,0\frac{D_{net}}D\\\end{array}\\2,5\frac{(n-1)(a²+b²)}{6Db}\end{array}\right.$

Values:
D Element thickness
D net Sum of longitudinal and transverse layer thicknesses in the element
n Number of board layers
a = b Width of the boards in the longitudinal or transverse layers

All values in N/mm². For more detailed information, check the manufacturer's approval.
