An experiment was conducted in a 20-level building, where 120 participants were asked to walk upward in the stair in four kinds of visibility conditions (i.e., normal visibility condition, lighting-out condition, the condition of wearing 27% transmittance eye-patch and the condition of wearing 16% transmittance eye-patch). Their upward movement, ascent speeds and behaviors were recorded by cameras. Read More...

This study presents the numerical modelling of a jetfan stream using an open source Computational Fluid Dynamics (CFD) software named Fire Dynamics Simulator (FDS) 6.5.2. The software is based on an accurate turbulence model named Large Eddy Simulation (LES) along with a structured mesh to discretize the numerical domain. This research is focussed on the feasibility and accuracy of modelling jetfans using FDS, where a simplified three-dimensional model is built to represent a single jetfan in an open-deck car park, to compare the air jet downstream of the jetfan using various mesh techniques. Read More...

This disaster management planning approach has been applied in a 123 stories super tall building located in Seoul, Korea. The purpose of this paper is to provide an overview of Pathfinder simulation application and propose a creative utilization to develop a disaster management plan in a super tall building project. Read More...

The aim of the paper is to carry out a comparison with and without platform screen doors in terms of evacuation conditions during a fire event. This way, it is possible to quantify and compare visibility, temperature, CO concentration and other variables in the evacuation routes. Read More...
