Hello Quique0185, If you put a V-stop support with a large gap up at this location instead of spring support you will see the following printed warning during the analysis of the model: W801-121: V-stop liftoff(s) have occurred under operating The question is how does your company deal with support liftoff? Select the hyperlink to see more details on this warning. About your modeling. You should try to make every effort to get the as-built information. Because running a Hanger selection could select different supports then what is actually in the field. I am sure that there are some kind of design documentation on this line you are modeling. If not, ask that someone go out to the field and get the spring hanger plate information. With regards about vibration, under what load case does the vibration happen? You may need to model some kind of dynamic loading. Regards, Mike Dattilio Bentley TSG Support Analyst ===================================================
