“…e research of bridge fires is still in its infancy, as fire experiments are expensive, and experimental results are influenced by various factors, resulting in large randomicity. Moreover, the structure in numerical simulation is divided into line units that are mainly based on one-dimensional or two-dimensional simplified methods [8,9]. Recently, the problems in the existing literature [10][11][12][13][14][15][16][17] in the study of bridge fire resistance are categorized into the following groups: (1) ermal engineering parameters and mechanical parameters of the research results are discrete.…”

This paper presents a numerical study on the high-temperature mechanical properties of a long-span double-deck suspension bridge. The main focus of this paper is the behavior analysis of Wuhan Yangtze River Bridge. A three-dimensional thermal model of the bridge was established by the Fire Dynamics software (FDS) to obtain the 3D temperature field distribution, and the thermal analysis result was then applied to the three-dimensional finite element model of the suspension bridge. The shortest failure time of the main cable and sling was determined to obtain the rescue time of a bridge fire. According to the calculation results of the suspension bridge under a tanker fire initiated at the upper deck of the bridge, the middle lane in the upper deck of the suspension bridge was determined to be a safe lane. Thus, the tanker should be guided to go in this lane of the bridge. The numerical analysis of the experimental results shows that when the fuel tanker is located on the upper and lower floors of the bridge, the bridge structure is affected by the fire. When the oil tanker burns in the outermost lane of the upper bridge, it will have a great impact on the main cables and slings of the bridge. When the fuel tanker burns in the lower nonmotorized lane of the bridge, it will have a great impact on the upper stiffening beam steel plates and truss rods.

“…Since then, several studies were undertaken, focusing on the thermal response of LPG tanks exposed to fire (Moodie (1988)). Lumped-parameter models (Aydemir et al (1988), Beynon et al (1988), Birk (1989), Dancer and Sallet (1990), Graves (1973), Heymes et al (2013), Johnson (1998b), Johnson (1998a), Ramskill (1988), Salzano et al (2003)) represent the simplest modeling approach to the problem, needing limited computational time and set-up parameters but usually neglecting important complicating phenomena such as the liquid thermal stratification and expansion (Landucci et al (2016a)).…”

Safety enhancement of operations in the chemical and petrochemical industry requires for advances in the tools aimed at supporting risk estimation and evaluation. In conventional risk studies, consequence assessment is carried out through simplified tools and conservative assumptions, often resulting in overestimation of accident severity and worst-case scenarios. Computational Fluid Dynamics (CFD) may overcome the limitation of simplified approaches supporting the study of the dynamic evolution of accidental scenarios and, eventually, the consequences analysis of major accidents. However, the complexity of the problem makes the simulations too computationally demanding; hence an interesting approach is to couple simplified tools based on integral models and CFD. This work is aimed at modeling a safety critical scenario, i.e. domino effect triggered by fire. An integral model is adopted to reproduce a large-scale pool fire, thus simulating the radiative heat received by an exposed pressurized vessel. The behavior of the latter is then modeled through CFD, to investigate the heat-up process and the consequent pressure build up. Potential benefits and limitations of coupling distributed and integral models to support consequence assessment studies are discussed

“…Pressure vessels are subject to various types of aggressive conditions that can weaken them and can sometimes lead to failure, e.g. corrosion, the impact of a projectile, or exposure to fire (Heymes et al, 2013).The case of fire engulfment of a vessel is investigated in this study because it is the most prevalent source of BLEVEs according to the literature (Abbasi and Abbasi, 2007;Hemmatian, 2016). In such a case the liquefied gas in the vessel is heated, increasing the pressure significantly.…”

This paper presents the results of a small scale experimental study of BLEVE overpressure effects. Testing consisted of a sealed aluminum tube (0.6 L) filled with either water or propane, being heated by a flame until the internal pressure led to catastrophic failure and explosion. Three parameters were controlled during the experiments: the failing pressure, the weakened length on the tube and the fill level. BLEVEs were obtained with tests involving water and propane. Blast gages and optical techniques were used to characterize the shock wave escaping from the failing tube. The results obtained suggest that the lead shock was primarily generated by the vapor space. Overpressure results obtained were compared with the predictions of existing models and found to be in reasonable agreement except for overpressures measured vertically above the cylinder where the overpressures were highest. A prediction model based on only vapor space characteristics was developed. Images show that the shock was fully formed at some distance away from the vessel opening and this was due to the non-ideal opening of the vessel. The model developed was based on the characteristics of the shock when fully formed away from the tube. These characteristics were defined using a combination of imaging, pressure measurements, and predictions from shock tube theory.
