Elevator Evacuation

Elevators are increasingly widely used in high-rise buildings. Because of its fast running, elevators, with great potential value and social requirements, are now days becoming very important traffic tools in high-rise buildings. However, it is an urgent problem to evacuate safely by using elevators during high-rise building fire accidents. This paper elaborates the necessity of elevator evacuation, analyzed the problem of evacuation by general passenger elevators. Some useful measures are put forward, such as fire prevention, smoke-proof, water-proof and emergency power supply for elevator evacuation during high-rise building fires. It is of great importance for us to utilize these measures for the evacuation by elevators during high-rise building fire accidents.

Elevator Evacuation

Elevator evacuation of high-rise building fire has become an urgent problem. Based on the problems of general elevator evacuation, this paper offers some measures of smoke-proof measures, such as setting up pressure ventilation in elevator car, setting up pressure ventilation in elevator shaft, setting elevator antechamber and setting smoke preventing air curtain etc. This paper provides some practical ways of elevator evacuation on high-rise building fire.

Smoke Flow

Purpose – The purpose of this paper is to study the behavior of smoke flow in a typical high-rise residential building fire in six common smoke control systems. Design/methodology/approach – The pressure, temperature and CO2 concentration were used to trace the motion of turbulent smoke flow through CFD. Findings – It is found that the hot smoke could rise up and spread into the indoor space on the upper floors through the staircase. When the pressure in the evacuation staircase is higher, it would be more difficult for the smoke to enter the staircase and transport vertically. On the other hand, the smoke would soon transport to the indoor space on the upper floors horizontally. During this process, the smoke shows a more disorder horizontal transport under the sole effect of thermal buoyancy than the co-existence of thermal buoyancy and the air inlet. Research limitations/implications – Because of the chosen research approach, the research results may need to be tested by further experiments. Practical implications – The paper includes implications for the design of smoke control systems and evacuation in a building fire. Originality/value – This paper fulfils an identified need to study the behavior of smoke in a fire and optimize the design of smoke control systems.

Firstly, this paper analyzed the factors affecting high-rise building fire safety in terms of the aspects of staff awareness, high-rise building fire design, fire-fighting facilities, daily management, and technology and so on. Secondly, on this basis, I determined the flow graph model and variables, and constructed high-rise building fire safety simulation model. Finally, a high-rise building was used to verify the applicability of the model. The findings have developed a clear direction in order to strengthen the management and formulation of high-rise building fire safety.
