Risk-based design and assessment methods are gaining popularity in performance-based structural fire engineering. These methods usually start by defining a set of hazard scenarios to use as analysis inputs. This approach, proven highly effective …
Eurocode-2 (EC2) empirical equation for fire resistance of RC columns is very sensitive to the value of column capacity at normal temperature conditions $$N_{Rd}$$ N Rd . Techniques to determine $$N_{Rd}$$ N Rd accurately for eccentric slender …
The adoption of timber, specifically cross-laminated timber (CLT), as a primary construction material is gaining traction due to its carbon sequestration capabilities, environmental advantages, and potential for precision manufacturing. However …

Aqueous film-forming foam is being phased out due to the environmental impacts of fluorinated surfactants contained in the firefighting foams. To develop an environmentally friendly firefighting foam, it is important to understand the factors …
This study is the first part of a larger investigation into the fire behaviour of green façades. In this study, the currently known international research status on this topic is presented and discussed. In addition, the flammability of green …
Providing NFPA 1403 compliant live-fire training can present thermal and chemical exposure risk to instructors and students. To reduce risk, training academies, fire departments, instructors, and standards setting technical committees need more …

In recent years, electrical fires, which constitute the majority of fire incidents, have become a significant concern. This paper presents a quantitative evaluation of the research on electrical fires from 1993 to 2022, using literature …

Recent experimental evidence has shown that wood–steel–wood dowel-type connections exhibit a semi-rigid behaviour even after 90 min of fire exposure. Because a semi-rigid behaviour influences the bending moment distribution among structural …
Fire statistics mirror the outcome of fire prevention. Most fire statistics in Germany deal with the loss of life, value, and fire department actions (number of interventions, nozzles used, or alarm category like a false alarm). However, these …

High-strength steel has been extensively used in numerous structures or high-rise buildings because of its high strength, ductility, and weldability. However, high-strength steel structures are vulnerable to fire hazards, so the ability to predict …
There is a need to revisit movement dataset(s) currently used as egress determinants to assess whether they are truly representative of the current diverse occupant base. This is particularly important with our aging population as these sets …

As the complexity and the cost of infrastructures have risen, the need for a fast, reliable, cost-effective and clean fire extinguishing system has become important. Water mist is a clean and effective technology to deal with most types of fires.
Connections are the most vulnerable parts of a structure under fire conditions. A novel steel connection with high axial and rotational ductility has been proposed with the objective to improve the performance of steel-framed buildings in fire.
Cone calorimeter tests were conducted to investigate the moisture transfer, burning and charring behavior of timber under fire heating. 99 × 99 × 50 mm glue laminated larch specimens were made in cross grain and straight grain directions. The …
In the frame of a research project, the structural behaviour in fire of cross-laminated timber rib panels were studied based on numerical investigations. The floor system consists of cross-laminated timber plates rigidly bonded to glued-laminated …
Fires can lead to costly building damage as well as loss of lives and injuries. Installed to protect buildings from fire, or to limit the damage from such outbreaks, fire protection measures are a common feature in buildings. However, these …

Closed ro-ro spaces on maritime vehicle carriers are usually protected by a total-flooding carbon dioxide system. Such systems have many benefits, for example that there are no residues that can adversely affect the protected objects (in this case …
Exploring fire resistance of high strength steel end-plate connections is one of the key technical bases for fire resistance design and fire safety assessment of high strength steel structures. Numerical simulation and parameter analyses of high …
Model-scale experimental tests and numerical simulations were conducted to investigate the characteristics of the smoke overflow at the lateral carriage doors and the smoke temperature below the tunnel ceiling of a carriage fire in a …
