How does the program or the user determine whether the connections are moment-transferring or non-moment-transferring?
 
Hello there; The program determines the element freedoms (support conditions) of the connections according to the experimental results as stated in the regulations. Joints made in accordance with the regulations have been used in steel structures for a very long time and there are many articles in the literature created as a result of studies on these joints. They already refer to these studies in the regulations. In short, the behavior of these joints is well known and engineers apply support conditions according to these behaviors. If a new combination other than the regulation is used in DBYBHY 2007, an experimental study has to be done to prove that this combination must meet certain conditions (for example, the amount of rotation) and comply with these conditions. If you want to get detailed information about the support conditions and behavior of the joints

You can access the FEMA documents. In the first part, there is also a list of FEMA documents related to other unions, it will be useful to review. Good work.
 
Hello there ; To give details programmatically, the program detects element freedoms according to the combinations you define. If you do not enter a union, you need to go to the properties of the elements and create the freedoms according to your moment-transmitting-non-transferring states from the element freedoms section in the menu. In the attached images, you can see which joints have which freedoms in the program, and for other joints, you can see how the element end freedoms are examined in order to control the analysis model.
