Performance-based Fire Safety Design of Reinforced Concrete Beams
A numerical model, in the form of a computer program, is presented for tracing the fire behavior of reinforced concrete (RC) beams over the entire range of loading from pre-fire conditions to collapse under fire. The three stages associated with the analysis of fire resistance; namely, establishing the fire temperature—time development, calculating the heat transfer through the structure from the ...

Integrated wildfire risk assessment: Framework development and application on the Lewis and Clark National Forest in Montana, USA
The financial, socioeconomic, and ecological impacts of wildfire continue to challenge federal land management agencies in the United States. In recent years policymakers and managers have increasingly turned to the field of risk analysis to better manage wildfires, and to mitigate losses to highly valued resources and assets (HVRAs). Assessing wildfire risk entails the interaction of multiple ...

Learning lessons from wildfires, from Texas to Brazil
“This is unprecedented fire behavior. We’ve never seen conditions like this before. Not a single one of our firefighters has ever faced such extreme conditions.” This statement from the director of the Texas Forest Service makes it clear that the recent wildfires that scorched Texas belong in a new category of disaster. Already, the state’s wildfires this season have ...

Does Your Fire Department Have a Rapid Intervention Team (RIT)
Fire departments are often tasked with handling emergency activities that can present to the responding firefighters a varying degree of risk and danger depending on the situation at hand. Rapid intervention teams (RIT), rapid intervention companies (RIC), and firefighter assist and search teams (FAST) all serve the same purpose to fire departments. They are there to facilitate their fellow ...

Mechanistic Analysis of the Fire Performance of a Fire Retardant System
The behavior of a fire retardant in polypropylene is studied in order to improve the understanding of its activity in terms of its chemical behavior. The effect of a N-alkoxy hindered amine light stabilizer upon the fire performance of this system is also considered. The authors relate fire performance (UL 94, OI, NOI) and thermal analyses (TGA and thin film FTIR) results to cone calorimeter fire ...

Evaluation of CFD Modeling Methods for Fire-induced Airflow in a Room
Methods for exploiting the technique of computational fluid dynamics (CFD) to model fires and the associated fundamental processes of combustion and radiation are appraised by applying the CFD model JASMINE to simulate the fire-induced airflow in a room-sized compartment. For a systematic evaluation of these methods describing the fundamental processes and the associated mathematical formulation, ...
