It is the third time we talk about mass timber and fire in this show, and I hope every time the message gets even more refined. In this episode, it is clear - fire resistance is not always enough. But why? You will learn that from dr Daniel Brandon from RISE who spent last years researching timber in fire. In this episode, we discuss the limitations of the fire resistance approach in testing timber structures, and also venture beyond it - how does exposed timber change the fire dynamics in a furnace and how in a real building? How the risk changes once you may have your structure participating in a fire, and why a 2-storey house is pretty safe, while a timber skyscraper brings challenges we have never met before. You may also want to view other important timber-in-fire discussions from the Fire Science Show:Episode 18 - Engineered timber with Danny HopkinEpisode 25 - Structural fire engineering with timber with Felix WeisnerPlease check the resources provided by Daniel:Exposure from mass timber to facadesFire Safe implementation of visible mass timber in tall buildings – compartment fire testingFire Safe Implementation of Mass Timber In Tall BuildingsAnd also, the most spectacular - see the large timber experiments on your own, to understand what Daniel meant with "the energy must go somewhere" - check this YouTube page
