What happens when the flames die down? It's a question rarely addressed in fire engineering, yet the decay and cooling phases of fires can be more dangerous than peak fire conditions. In this deep-dive conversation with Dr. Andrea Lucherini from Frisbee at ZAG in Slovenia, we uncover why these overlooked phases matter profoundly for structural safety. Most engineers focus on protecting structures during the fully developed fire phase, but as Dr. Lucherini reveals, catastrophic failures can a...
