1. 1. Assessment of People's Perception of Fire Growth: A Virtual Reality Study

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Francisco Rosero; [2017]
   Nyckelord :Virtual Reality; Fire Growth; Estimation; evacuation; emergency; Technology and Engineering;

   Sammanfattning : One important aspect that is considered when designing safer buildings is human behavior. A comprehensive assessment of how people react during a fire, provides engineers valuable information, which will allow them to develop effective solutions to help people reach a safe place under tenable conditions.

3. 2. Probabilistic study of number of doors open simultaneously to fire-isolated stairs in basement carparks

   Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Josefin Nilsson; [2017]
   Nyckelord :Carpark; basement; evacuation; stair pressurization; CarParkEvac; fire-isolated stair; pre-evacuation time; movement time; travel speed; travel distance; conceptual model; probability; probabilistic method; distributions; calculation model; simulations; case study; sensitivity analysis; Technology and Engineering;

   Sammanfattning : This thesis investigates occupant evacuation in basement carparks. The thesis aims to develop a calculation model to determine the probability of different number of doors to fire-isolated stairs being open simultaneously during an evacuation scenario. LÄS MER

4. 3. MassMotion Evacuation Model Validation

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Mohammad Mashhadawi; [2016]
   Nyckelord :Evacuation Modelling; Verification methods; Validation methods; Functional analysis; Behavioural uncertainties; Walking speeds; and MassMotion.; Technology and Engineering;

   Sammanfattning : The thesis purpose is to validate a set of functionalities of MassMotion. MassMotion is an evacuation model that can simulate the pedestrian movement in a 2D environment and visualize it in a 3D environment. LÄS MER

5. 4. Verification and Validation of Viswalk for Building Evacuation Modelling

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Johan Henningsson; Johan Blomstrand Martén; [2015]
   Nyckelord :Viswalk; evacuation model; egress model; verification; validation; Technology and Engineering;

   Sammanfattning : This thesis is evaluating the pedestrian modelling software Viswalk for the use as a building evacuation model, by verifying and validating the model. In the verification, a procedure from the National Institute of Standards and Technology (NIST) is used as a basis to assess Viswalk’s ability to represent pre-evacuation time, movement and navigation, exit usage, route availability and flow constraints.
