| Abstract |
Under the Korean Enforcement Decree of the Building Act, all of high story apartment houses more than 5 story buildings are mandate to
install fire evacuation system to ensure safe evacuation from fire accident providing quick and easy bi-directional escape route when main
entrance is blocked by flame and toxic smoke caused from fire. However, current fire evacuation system shows lack of understanding from
residents and thus widely ignored for having insufficient safety functions especially on fire emergency. Studies found that recent changes in
housing characteristics through improvement of living has lead applying various planes into dense and multipurpose floor space for convenient
residence trend while conventional passive fire evacuation system such as indoor shelter space, light-weight partition and top-down emergency
exit are still installed without improvement on fire safety which may cause unsuccessful evacuation especially when residential buildings are
raising high. An alternative high rise building evacuation method, so the called escapable fire evacuation system has analyzed for safety
evaluation compared with conventional passive stay able fire escape system that can bring efficient and safer solution providing high rise
residents escape from fire accident. Evaluation for safety evacuation on active fire escape system has performed by Fire Dynamics Simulation
and applying Pathfinder simulation, resulted in providing proper and appropriate escape route within the safety escape time allowed for
multiple residents including disabled and elderly persons in high rise building fire. |
