  1. 16. Mescape - A probabilistic mesoscopic model for fire evacuation in large gatherings

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Lorenzo Contini; [2022]
    Keywords : Human behaviour; crowd evacuation; mesoscopic modelling; hydraulic model; large gatherings; fire safety; performance-based design; quantitative risk assessment; consequence analysis; uncertainty analysis; probabilistic modelling; Technology and Engineering;

    Abstract : This study presents a mesoscopic model that predicts pedestrian evacuation in large gatherings with probabilistic methods. The model is based on a coarse network representation of buildings, where occupants are treated at a different scale according to their location. READ MORE

  3. 17. PRESCRIPTIVE AND ACTUAL OCCUPANT LOAD OF BUSINESS PREMISES IN FINLAND BEFORE AND DURING COVID19

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Timo Rantamäki; [2022]
    Keywords : Occupant load; Occupant load factor; Finland; Technology and Engineering;

    Abstract : The purpose of this thesis was to study the correspondence of occupant load factors determined by the guidance document of Finnish National Building code and the real occupant loads measured from shopping malls. The correspondence of occupant load factors determined according to Finnish National Building Code were compared with the occupant load factors determined in other national and international building codes.

  4. 18. Visibility in Smoke With Different Extinction Coefficients

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Lea Elhokayem; [2022]
    Keywords : Visibility; smoke; exit sign; extinction coefficient; visibility constant; evacuation; Technology and Engineering;

    Abstract : Visibility in smoke has since the 1970s gained some attention, mostly after Tadahisa Jin ran the experiments which helped him develop todays widely used visibility equation. By showing that visibility can be assumed to be inversely proportional to the extinction coefficient by a visibility constant (equal to 8 for light emitting sign and 3 for light reflecting), Jin opened up new doors for researchers who were testing out his theory by going around experimenting in different ways and also by showing that there is way for more research to be done.

  5. 19. Validation of WUI-NITY compared to real-world data

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Jonatan Edenvik; [2022]
    Keywords : Wildland urban interface; Wildfires; Community evacuation; Real-world simulation; WUI-NITY; PeMS; Pedestrian simulation; Traffic simulation; Technology and Engineering;

    Abstract : This thesis compares the wildfire evacuation simulation programme, WUI-NITY, against real-world data by analysing and comparing three wildfire events of the past. The wildfire events were all limited to be within the state of California and was further analysed based on the available quality of data derived of the chosen database. READ MORE

  6. 20. Verification Testing of Evacuationz, a Coarse Network Evacuation Model

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Antariksh Gupta; [2022]
    Keywords : Technology and Engineering;

    Abstract : Several evacuation models exist in the market. It is an issue for both the user and developer to evaluate the ease of use and the quality of the model results. Verification is the process of determining that the results of a calculation method match with the developer's conceptual modelling representation expectations, i.e. READ MORE
