Objective of the course lie in basic information about thermal and mechanical loading and their combinations during exceptional situations, mainly during fire and blast. Theoretical foundations of heat transfer are discussed. The main part of the subject is focused on modeling the temperature for different types of fire and its effects on the bearing structures. The conclusion is devoted to the issue of explosions, modeling of pressure waves and their effects on buildings.


The student should be familiar with the loading of structures in common situations and with the basics of physics.
