By default, any member that is not in the XZ or YZ plane is considered a brace. It can be designed as a column, but internally ETABS will call it a brace.
I have previously defined columns in section designer with a few reinforcing patters and column strength and during design checked the column for strength using the interaction curves generated.
What is a good example of a structure that has a sloped column?
In any ways, my idea is to get the forces and manually design it using any spreadsheet available. Ignore the description of etabs as a brace.
