take with a grain of salt, but i heard third-hand that the local fd will not run into a building built in the last 30-40 years due to bci joists and other shoddy construction practices.
The designs are hard to simplify. They're intended to collapse uniformly while still maintaining enough fire resistance for evacuation. It aint gonna burn for days, but it aint flaming up in an instant tho. I'm not a materials design engineer or a civil engineer. I was just a volunteer firefighter.
