Elevator Evacuation

This paper presents the input and output of elevator evacuation warning system based on the analysis of elevator evacuation risk in fire, and expounds elevator evacuation warning system design concept from three aspects, which are "use of the elevator is safe", " waiting for the elevator is safe" and "elevator's decision is a safe choice".

Elevator Evacuation

As tall buildings are becoming more common there is a need to examine alternative evacuation strategies. In response to this many new high-rise buildings are equipped with evacuation elevators. Traditionally, elevators have not been used for evacuation and people have been instructed to avoid using them in fire emergencies. It might therefore be quite challenging to get people to use elevators for evacuation. If evacuation elevators are to be perceived as an attractive option people must be given appropriate information and guidance. In the following paper, previous research is examined in order to identify the information required to convince people to use evacuation elevators. In addition, a theory that can aid the design of evacuation systems, i.e., the tools for conveying the information, is presented and applied. Finally, a research strategy for developing and testing new evacuation systems is presented.

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.

Elevator Evacuation

Issues revolving around the use of elevator evacuation in highrise buildings for emergencies (both firerelated and nonfire-related) have long been under debate. This research investigates the performance of using elevator evacuation in Taipei 101, the second tallest building in the world. Taipei 101 Financial Centre (the main building) is used mainly for office occupancy and contains a total of 61 elevators. The analysis for this study was carried out using simulation results from building EXODUS and FDS. The results show that using elevators as a method of evacuation can help shorten up the time in a nonfire-related emergency, but in the case of fire events, elevator evacuation is less effective due to the nature of the structural layout, reliability of electric power and other factors. The results for nonfire-related evacuation time found in this study correspond to some literature on elevator evacuations from abroad.

Elevator Evacuation

Long evacuation time is a key fire safety concern for crowded supertall buildings. Elevator evacuation appears to be the only choice but fire safety provisions are not specially designed for the use of elevators. A fire safe elevator system was proposed earlier for supertall buildings by providing elevator accessible on each floor level and passing through the refuge place. The fire hazard associated with this design has been studied numerically through an example building in this paper. Smoke spread to the elevator system was considered in the study. The effect of ventilation of the shaft, stack effect and wind effect on smoke movement were studied by empirical equations in fire engineering and justified by computational fluid dynamics. Different designs of smoke extraction with pressurization system were evaluated by analysing the smoke dispersion and pressure distributions. The effect of fire at different heights on smoke spread was also investigated. Results show that the smoke extraction system can only delay smoke spread to the elevator shaft near the fire source for a short time. The “four-floor approach” pressurization system can confine the smoke in the area of fire floor for a sufficiently long time period for safe evacuation.
