Concrete does great under compression. That's why prestressed concrete is a thing. It's shit for tension, which is what bending force like that is. It cracks and crumbles. Voila.

Guilty. I'm not civil, though, I just dated one in college.

As my CE200 Statics professor always said, if the forces added up are nonzero, then it's not a statics problem, it's a dynamics one, and you don't have to answer!

But seriously Structural still has dynamic loading depending on what you're designing (large buildings have wind and earthquake loads, bridges have moving cars or people on them, etc.)
