One environment that hinders the performance of reinforced concrete is fire. In most cases, this results in the affected part or the entire structure being rendered useless or completely collapsing. When fire mishaps happen in structures, this is …

The main objective of this paper is to use the residual strength theory to study the probability of a domino effect accident occurring following the explosion of a spherical tank. We build a novel domino effect accident probability model, using …

Nowadays, significant research effort is being dedicated to explore environmentally friendly block materials with high strength and high-temperature resistance. Ground-granulated blast-furnace slag (GGBFS) is produced during the iron smelting …

The knowledge of the fire safety distance of the multiple pool fires is essential to model, manage, and mitigate the fire hazardous scenarios to safeguard the surrounding people, buildings and equipment. In this work, experiments are performed on …

Aqueous film forming foam (AFFF) has been the industry standard for combatting liquid fuel fires and hazards for almost 50 years. AFFF is a water-based solution that contains a fluorinated, film forming surfactant [per- and poly-fluoroalkyl …

Experimental analyses and numerical simulations are carried out on a test case involving an heptane pool fire within a large under-ventilated environment. During the experiments, the temperature history at several locations within the room is …

The mechanical properties and nonlinear performance of the Q960 cold-formed thick-walled ultra-high-strength steel (CTUS) after elevated temperatures were investigated experimentally, where the effects of cold-forming process, elevated …

The goal of the present work is to establish a framework for firebrand morphology characterization. Central to this framework is the development of a simple firebrand shape classification model using multi-dimensional particle shape descriptors.

This study aims at utilizing machine learning (ML) in predicting the fire resistance and spalling degree of reinforced concrete (RC) columns with improved accuracy and reliability. A database with 119 test specimens was created for the development …

This work concerns how to effectively detect the fire in early stage using computer vision method. As known, the flame of early fire is small and cannot be effectively detected by traditional fire detectors. Inspired by color characteristics of …

The traditional storage method of fire accident cases is mainly in the form of text, and it is difficult to effectively conduct comprehensive analysis due to the limited ability to display key information and fire knowledge. In this paper, a …

Fire accidents are more likely to occur in tunnels with different curves, aspect ratios, and slopes due to the land’s geographical characteristics. A three-dimensional computational fluid dynamics code with curvilinear grids fitted to the body was …

The mechanical material behavior of mild steels is reversible in the cooling phase of natural fires, which is proven by experimental evidence. For the material behavior of high-strength steels during cooling, no results are yet available. The …

The fire resistance and the thermomechanical behaviour of Steel–Timber Composite (STC) beams are studied through 4 fire tests. 35 non-loaded reduced specimens and 2 mechanically loaded real-scale beams were tested considering standard fire …

Fire testing enables an individual or an organisation to make a claim about how a material, product, or system will perform in operational use. This paper describes and analyses the various reaction-to-fire tests that have used over the last 100 …

The effects of the slope and the trench inclination on the spread of wildfires with a homogeneous fuel bed in inclined trenches, were studied numerically by Fire Dynamics Simulator. This simulation is based on a solid–gas two-phase numerical model …

Concrete-filled hollow section (CFHS) columns with a solid steel core have gained popularity in the construction of tall buildings due to their robust load-bearing capacity, slender design, ease of prefabrication, and exceptional structural fire …

Large and downed woody fuels remaining behind a wildfire’s flame front tend to burn in a smoldering regime, producing large quantities of toxic gases and particulate emissions, which deteriorates air quality and compromises human health.
