Modeling the Dynamics of Fire and Evacuation

The course 124YMPE can be graded only after the course 124MDPV has been successfully completed.

Garant předmětu:

Petr Hejtmánek, Vladimír Mózer, Marek Pokorný

Lecturer:

Petr Hejtmánek, Vladimír Mózer, Hana Najmanová, Marek Pokorný

Tutor:

Petr Hejtmánek, Vladimír Mózer, Hana Najmanová, Marek Pokorný

Supervisor:

Department of Architectural Engineering

Synopsis:

The course is focused on current topics of fire engineering (the so-called performance-based design) in the area of specific behavior of people during evacuation and fire dynamics in buildings. The content builds on the previous basic knowledge of the students in the prescriptive evaluation of fire safety of buildings using standard procedures, table values, or simplified mathematical relationships. The course is also focused on the advanced fire engineering approaches to fire safety design, the principles of fire dynamics and development in the closed space of the building in the form of analytical relationships and mathematical simulations (zone fire models), including modeling the behavior of people during evacuation.

Study Objective:

The aim of the study is to familiarize students with the fire engineering approach to fire safety design of buildings and prepare them for its use. For this purpose, students will acquire theoretical knowledge and practical experience in the following key areas: formulation of objectives, criteria and scenarios for analysis, characteristics of people and detailed assessment of evacuation options, characteristics of fire and its modeling, analysis of obtained data, their evaluation and formulation of conclusions.
