How to model one bolt connection

Sometimes, engineer needs to make a joint with one bolt only, especially if hinge is wanted. To model and calculate this kind of operation, we need to use a certain Model type.

 

If we use standard Model type: N-Vy-Vz-Mx-My-Mz on member connected only with a single bolt, the mechanism/singularity can occur or the check will not be performed.

 

We have to change the Model type: to N-Vy-Vz in Properties of appropriate member.

 

Now, the model is correct and mechanism is prevented.
