Mechanically Jointed Beams
The program HNV+ is used to design mechanically connected wooden beams. Different timber cross-sections can be stacked and connected by means of fasteners. The various elements can be of different timber materials and the fasteners can have different spacing.

Ultimate limit state
In the ultimate limit state, both the initial and the final state are calculated. This provides for compliance with the standard, which requires that when the distribution of internal forces is influenced by the stiffness distribution, the deformation coefficient affects the moduli of elasticity, shear, and displacement.
Method of shear analogy
The design is performed using the method of shear analogy. Two virtual beams are generated which are coupled in their deformation but have different stiffnesses. The stresses of the two beams are then used to perform the verifications.
