I've always wondered about that and how human fear may override training and advice.

Seems like you would be fighting the part of your brain telling you it's (solely) /your/ building collapsing and you need to get out

And wondering if the building is up to code, and trusting that in the moment

Training and advice is about the expected disaster, not necessarily the one you are in.

In 9/11, lots of people escaped the south tower using elevators, which is the opposite of what you're told to do. There are people who died because they chose to follow the stair route. But others died because they were trapped in elevators.
