- Keep an eye on the detailing at the connections to whatever you're connecting to at the member ends. Usually this makes for somewhat painful shear/punching shear considerations.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
