What is the note 40162 saying regarding the shear strengths of Binderholz company?

Answer

For the superstructures of the manufacturer Binderholz, as soon as the slabs are defined without glue at narrow sides and design of shear failure is calculated in the wall plane, the shear strengths are calculated according to the following equation.

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

Values:
D element thickness
Dnet 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.
