Opening in the column's web

[Anonymous]

Hi!

I need to model a column with an opening in the web. I want to know if it is possible, and if, how is it done?

Im using Robot structural Analysis version 2012

Best regards,

Hi again!

Could you please give me a more detailed description, the hole must be a rectangular one. Is it possible to model the hole on a already existing column? If not, have do I make the column a shell element? Im a novice, the more  detailed description, the better.

Thank you!
