Fire Behavior in a Hermetic Pressurization Building for Reducing the Effects of High Altitude: A Case Study

Hermetic pressurized buildings have been developed to reduce the effects of high altitude. The behavior and effect fire in this new type building not studied before. Unlike common buildings, inside pressure is maintained at around standard atmospheric pressure, which significantly higher than outside environment altitude regions. In addition, early stage a fire, oxygen required maintain combustion sealed supplied by mechanical vents (if operation) instead opening windows or doors as buildings. This paper presents case study on hotel located Tibet. Fire dynamics simulator (FDS) used under different design scenarios. Available evacuation time scenarios are obtained analyzing concentration, gas content, temperature, visibility other indicators. Based this, protection scheme suggested.
