How to put rotational stiffness into your FEA model

The stiffness of the joint is a significant and indispensable factor in the design of the global structure for semirigid connections. The question is, where can I calculate the stiffness of the joint, and what stiffness should be used for my design? 

The video below explains all aspects of the design.
