Answer:
In the case of cross-laminated timber plates that are not bonded on the narrow sides and a wall-like structural behavior, the torsion stress in the glued joints is often governing. This design is performed according to the explanations in the literature source given below, using the following equation.where
- b is the board width,
- n is the number of board layers,
- nxy is the shear in the layer plane,
- is the shear of board layers,
- is the shear in the thickness direction,
- fR is the rolling shear strength,
- fv,tor is the torsional shear strength.
For the y-direction, the design is similar, but using the values for the y-direction.
