Numerical Simulation Research on Vertical Fire Spread Control on the Outside of Super High-rise Building

Abstract

Aiming at the problem of vertical fire spread of exterior walls of super high-rise buildings, the measures to prevent the fire spread of the exterior walls are given in two aspects: the vertical fire separation between standard floors and the vertical fire separation between function sections by refuge floor. The numerical simulation method is used to study the characteristics that the fire smoke flow vertically spreads through the exterior walls. The simulation results show that under the disadvantage of fire extinguished failure, glass curtain walls of the adjacent floors will not break down, and the hot smoke of fire floor will not spread into the adjacent floors by outdoor ways. Even if the curtain walls of adjacent floors break down, the hot smoke in the fire floor will not ignite the indoor combustibles of the adjacent floors by outdoor ways, and the fire will not spread into the adjacent floors.
