1) I have a column that is modeled on a extended cantilever and I have an error shown below. When the same column is modeled on a stub cantilever, the error does not show up. Could you explain what might be the reason?
2) Also, is it possible to create a discontinue column between floors?
You can't place a column supporting the tip of a cantilever as that would be indeterminate. Nor can two cantilevers frame into each other tip to team. See: communities.bentley.com/.../ram-ss-modeling-faq
Seth, the column is not supporting the cantilever. It is modeled on floor above. Hence, wouldn't that be just a cantilever beam with point load at the tip of the beam? Would that be a statically determinate beam? How would you model that if we want to model that condition?
Also, could you help to clarify if it is possible to discontinue column between floors?
Thanks. WeiPhang
If the column is on a higher story, supported by a cantilever below that would be OK, (not what the picture looked like to me). A column can be discontinuous. Remember, you are always modeling the column that goes down from the current framing plan. Columns above can be shown in reference layouts.
Thanks. You're right and that was the intent on the floor above. Would it be possible to analyze statically indeterminate beams in RAM SS? Would it work if it is modeled as a frame elements and analyze it in that module?
If you re-read the link I initially sent (communities.bentley.com/.../ram-ss-modeling-faq) it explains some of the indeterminate scenarios that are commonly modeled in RAM SS (continuous beams for example). Most things can be modeled using lateral members with the correct fixity.
