Modelling pedestrian merging in stair evacuation in multi-purpose buildings
(2018) In Simulation Modelling Practice and Theory 85. p.80-94- Abstract
Despite the total evacuation time of occupants in a multi-storey building not being affected by pedestrian merging on stairs, the calculation of evacuation times in each individual floor depends on the pedestrian merging ratio. In fact, different merging ratios may cause an evacuation to take place from the top to the bottom or vice versa. A simplified simulation model for the calculation of evacuation time at each floor is presented here. This model allows the investigation of the impact of two main variables affecting the evacuation time at each floor, namely 1) different initial numbers of pedestrians at each floor (i.e. occupant load), and 2) different merging ratios at each floor. This means that the model allows the calculation of... (More)
Despite the total evacuation time of occupants in a multi-storey building not being affected by pedestrian merging on stairs, the calculation of evacuation times in each individual floor depends on the pedestrian merging ratio. In fact, different merging ratios may cause an evacuation to take place from the top to the bottom or vice versa. A simplified simulation model for the calculation of evacuation time at each floor is presented here. This model allows the investigation of the impact of two main variables affecting the evacuation time at each floor, namely 1) different initial numbers of pedestrians at each floor (i.e. occupant load), and 2) different merging ratios at each floor. This means that the model allows the calculation of the evacuation time at each floor considering a building with different occupancy types at different floors (e.g. office, residential, commercial, etc.) and different merging ratios which may be caused by a different configuration of the landing door at each floor. The model is presented in this paper using a case study of a hypothetical building. A detailed discussion on the model assumptions, advantages and limitations is also provided.
