The course is a substitute for:
Fire and Explosion 1 (102POV1)
Lecturer:

Tutor:
Zdeněk Sokol (guarantor), Petr Semerák, Vítězslav Vydra
Supervisor:
Department of Steel and Timber Structures
Synopsis:

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.

Requirements:

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

Syllabus of lectures:

1. Introduction, basic thermophysical properties, heat conduction equation

2. Heat conduction in solid materials, boundary conditions

3. Heat transfer by convection and radiation

4. Introduction, mechanical load in an extraordinary design situation

5. Density of fire load, heat release rate, fire scenarios

6. Nominal temperature curves, parametric curve. Transfer of heat to the structure, protection of structures against the effects of fire

7. Zone models, Ozone program, CFD analysis

8. Local fire, fire assessment in covered garages

9. Structural analysis in fire, video on fire test at Cardington

10. External elements, heat transfer by radiation

11. Introduction to explosion theory, types of explosions

12. Explosives and their characteristics, Determination of explosion response

13. Design of structures for pressure wave loading, evaluation and documentation of post-explosion traces

Syllabus of tutorials:

1. One-dimensional heat conduction

2. Heat transfer by convection

3. Heat transfer by radiation

4. Density of fire load, rate of heat development

5. Temperature according to the standard and parametric temperature curve

6. Temperature of unprotected elements of a steel structure in a fire

7. Temperature of the protected structural elements in a fire

8. Temperature by zone model

9. Heat temperature in the steel hall at local fire

10. Simplified analysis of frame construction at (local) fire

11. The temperature of the steel column in front of the window of the fire department

12. Theory of explosion

13. Design of structures for pressure wave loading

Study Objective:

The aim of the course is to acquaint students with the modeling of the course of temperature during fire in various objects and its effects on building constructions, calculation of design combinations of thermal and mechanical loading in extraordinary situations and with effects of explosion on structures.
