Abstract：
Based on the standard of GB 50016-2014 Code for fire protection design of buildings, analyses different modes of the ducts penetrating building external walls for ventilation, air conditioning, fire protection and smoke control systems. From the viewpoint of preventing the spread of fire, discusses whether fire protection measures should be adopted when the ducts penetrate building external walls. Investigates common potential risks of the ducts penetrating building external walls, and gives some relevant solutions.
