Abstract

In order to explore influence of incentive mechanism on high-rise building fire evacuation, potency, expectation and instrumentality were analogized in evacuation studies by using Vroom ' s expectation theory, potential value that evacuees can be stimulated was quantified and its impacts on evacuation speed were analyzed. Then, with fire evacuation of a high-rise commercial building as an example, influence of incentive mechanism on evacuation speed was introduced and compared with cases without considering it. The results show that with incentive mechanism, it takes 500 s to evacuate which will be 630 s otherwise. The former has higher evacuation efficiency as a whole while that of the latter is close to 0 after 520 s. Incentive mechanism significantly increases human body's tolerance limit of fire products, reduces impact of smoke on evacuation speed in early stages of fire, and delays life-threatening time point, thus improving evacuation efficiency indirectly. © 2020 China Safety Science Journal.
