The aim of the course is to acquaint students with the principles of ensuring fire safety of buildings using advanced methods of fire modeling, heat transfer to the structure and the behavior of the structure at elevated temperature when exposed to fire. Teaching is focused on the use of numerical modeling by the method of zone models and CFD (Computational Fluid Dynamics) used for the calculation of temperature field, FEM (Finite Element Modeling) used for the calculation of heat transfer and mechanical behavior of structures, which include both parts of the calculation. In the part focused on numerical modeling is also highlighted the issue of inputs into software tools. Possibilities and pitfalls of determination of inputs needed for CFD and FE models are explained, with the main focus on fire technical characteristics (PTCH) of materials. Emphasis is also placed on a suitable way of verifying the results by means of model verification and validation. This section includes an introduction to benchmark cases. Verification is closely related to the physical testing of structures. Teaching includes an experimental part. Several type tests are prepared for experimental teaching. It is a test of gas temperature measurement (elevated temperature from the radiation panel is measured using various types of sensors, the results of which are subsequently evaluated), tests of heat transfer to structures (in concrete, steel and timber elements are measured temperatures at different depths, with numerical models).
