This paper analyzes in detail the design of anti-smoke stair-half,natural smoke exhaust windows in atria and combined atria of high-rise civil buildings,and puts forward some modus operandi.

Study and application of natural smoke evacuation mode for metro section tunnel fire;

In this paper,performance-based fire safety design concept was adopted to analyze the fire safety objective that the smoke evacuation system of Laoshan bicycle racing centre should achieve,fire scenarios were designed and the performance of natural smoke evacuation system was studied by using CFD techniques.

It illustrates the importance and main contents of designing smoke abatement and evacuation facility in building,introduces the installation method of natural smoke evacuation and mechanical smoke evacuation,analyzes the causes of irrational installation in practical engineering,and proposes supervision management measures in its construction.

Numerical simulation and evaluation of natural smoke exhaust for straight corridor in high-rise buildings;

Describes briefly the basic concept about natural smoke exhaust calculation, such as thermal pressure,steady state fire, neutral level, flow coefficient, etc.

Quasi-steady state of natural smoke exhaust with natural air makeup under surrounding winds was studied using a simple two-layer zone model.

Describes the design approach to gravity smoke venting .
