Tips & Tricks

In the third part, we already mentioned that for a wall‑like load‑bearing behavior of the cross‑laminated plate, special attention should be paid to the in‑plane shear lag, and thus in particular to the displacement of the fasteners.

The slip of a timber wall is computed by using the slip modulus. For a 4 mm nail in a common C24 timber, we obtain a slip of 793.981 N/mm per shear plane. Now, all that is left to do is to consider the mean value of the stiffness and the partial safety factor, which is omitted in this example. The distance of the used nails then gives the necessary longitudinal stiffness of the joint.

In the next post from this series, we will look at the design of the fasteners.
