Structural Fire Engineering Episodes

Today we talk fire resistance, but unlike you have ever heard. Join me and Dr Piotr Turkowski - two fire laboratory professionals in an honest discussion about their craft. The challenges in standardization and committee work, discoveries in laboratories that are very tough to implement in the test method design, and sometimes unscientific approaches which are necessary for a market consensus. All the challenges that make us view fire resistance in a different way than you may have. Here are so...

I wonder if we will be ever able to say: we know exactly how to build fire-safe buildings with mass timber. However that day may never come, each day of research brings us a little bit closer to achieving this goal. And some days - like the one in which Andy Buchanan and Birgit Östman published their open access handbook on fire-safe use timber, we definitely leap towards success! In today's episode, I'm interviewing prof. Andy Buchanan on his thoughts on fire-safe use of timber, in relation to...

The relation between ventilation conditions and fire severity is quite a fundamental one. You don't even have to be a fire safety engineer to realize that more air means a bigger fire. But how does air get into the compartment fire in the first place? Through broken windows of course! And here we come to the subject of today's episode. Because with all the considerable improvements in glazing technologies for building facades, is it really okay to assume that the glazing has failed and all we ...

The subject of structural fire engineering was long overdue in the podcast schedule. But once I finally got it on my agenda, I made sure to interview one of the very best there are - prof Thomas Gernay of John Hopkins University. Not only a structural engineer and researcher, but also one of the developers of SAFIR® - one of most popular structural fire engineering numerical codes out there. In this discussion I get to ask some important questions on the role structural fire engineering plays i...

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 fur...

If you have ever learned about the compartment fire dynamics framework, have tried zone modelling or any kind of fire modelling, you have probably noticed that as the compartments get bigger, the less uniform conditions inside are. At some size, the flashover or a "single-zone" model theories just break, MQH equation does not give a reasonable solution and the fire seems not capable of growing to a huge size... But yet, they destroy buildings. Local fire exposure may be damaging to structural el...

In Episode 18 we have touched on the important topic of fire performance of engineered wood and its wide use in the modern built environment. Today, we follow up on this subject with Dr Felix Wiesner from the University of Queensland. We leave the (important) topic of compartment fire dynamics and focus on what happens inside the wood in the fire. And there is much more going on than I have initially thought... The transport of moisture, weakening bonds at the glue line and connections, complex ...

Risk as a concept is well established in modern Performance-Based Design in Fire Safety Engineering. However, it comes in many flavours - from a simple calculation of consequences vs probability, through indexing methods and using some arbitrary measures (number of fatalities, cost of damage etc.). Most of these methods focus on the value or threshold of the risk... while my today's guests seem to focus much more on the process itself. Today I'm happy to host Dr Jaime Cadena Gomez (UQ, Transurb...

It is hard for us, fire safety engineers, to talk to firefighters on how to do their job... Probably we even shouldn't, as we have no idea how it is to truly go there into the heat and battle fire to save lives. But it does not mean we should not care. Firefighters are important actors in the fire safe world, and we cannot design buildings as if they were not. In the end, the probability of you being in a fire is fairly low, while for a firefighter this P = 1. Our decisions shape the building en...

Engineered timber is on a trajectory to become the construction material of the future. However, on that pathway there stands the fire issue. Wood burns, it is inevitable. This is something we must accept, and learn to work around. Common approach – determination of a char profile and the “healthy” section has its limitations, especially when applied to CLT products in which one could expect the glue line failure. And all of this is the topic of my todays discussion with Dr Danny Hopkin of OFR C...

Did you know that the standard temperature-time curve, which is the underpinning of the fire resistance of assemblies, is over 100 years old? Once you know that, you cannot stop but think about how this affects modern construction works. In this episode, I'm interviewing dr John Gales from York University, who has spent over a decade studying the historical origins of fire testing and the standard curve. John has found some missing links and narratives and has also done a pretty good job confron...
