We introduce an open-source software Aamks for fire risk assessment. This article focuses on a component of Aamks – an evacuation simulator named a-evac. A-evac models evacuation of humans in the fire environment produced by CFAST fire simulator. In the article we discuss the probabilistic evacuation approach, automatic planning of exit routes, the interactions amongst the moving evacuees and t...

This paper presents a methodology for evaluating life safety risks in road tunnel fires. The methodology considers three realistic fire scenarios, smoke spread, occupant evacuation, and reliability of fire suppression systems. The three fire scenarios represent three variations of fire growth rates. The road tunnel in this study is assumed to have two traffic tubes, a longitudinal ventilation s...

Recent studies have shown that vertical greenery systems (VGS) carry a significant fire threat when not properly looked after. Building on this, the hazard of VGS was compared to two other thermally efficient building façade (TEBFS), namely external thermal insulation composite (ETICS) and double-skin (DSF). Numerical simulations were conducted in dynamic simulator (FDS). A initiated as room 1 ...

Many obstacles exist in attempting to graphically render physical phenomena that are highly fluid and ostensibly chaotic in nature. Fire is a prime example of such phenomena. Given the unrealizable computational complexity of chemical-atomic modeling, this paper explores how to best apply our current understanding of the physical fire model to balance computational stresses for optimal realism....

Forest fires are time evolving disasters that consume environmental and financial resources, endangering the rescue units that try to mitigate them. As such, a simulator that can predict the fire propagation is essential to locate control systems, in order to reduce the loss of natural resources without risking the firefighters. This paper proposes a simulator based on discrete representation o...

Cultural heritages and historical buildings are vulnerable against severe threats from fire. Since the 1970s, ten fire-spread events involving historic buildings have occurred in Taiwan, affecting a total of 132 nearby buildings. Developed under the influence of traditional Taiwanese culture, historic buildings in Taiwan are often built using non-fire resistant brick-wood structure and located ...
