Stone doesn't burn, and neither does concrete. Glass melts. Steel evidently didn't burn at the temperatures these fires got to. So it makes sense that a building made of concrete and steel with stone facades and fiberglass insulation would survive the fire, especially after clearing out and hydrating the surrounding landscape so it wouldn't have the density or flammability of a forest. The Getty Center may have gotten lucky, but they might have also earned their "luck" through investment and planning.
