Note 40162: Shear Strengths for Truss Structures Without Narrow Side Bonding

What is the meaning of Note 40162 concerning the shear strengths of the Binderholz company?

Answer:

For layer structures by the manufacturer Binderholz, as soon as the slabs are defined without narrow side bonding and a verification of shear failure in the plane of the pane is assumed, the shear strengths are calculated according to the following equation.

f_{v, k} = \{\begin{cases} 3.5 \\ 8.0 \frac{D_{net}}{D} \\ 2.5 (\frac{(n - 1) (a^{2} + b^{2})}{6 \cdot D \cdot b}) \end{cases}

D	Element Thickness
D_net	Sum of the 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

Shear Strengths

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