Supervisor:

Department of Steel and Timber Structures

Synopsis:

In the subject, students will learn about advanced models for designing steel, concrete, steel-concrete and wooden structures exposed to fire.

The teaching is focused on advanced modeling combining fluid dynamics with thermal and mechanical analysis using the finite element method.

Requirements:

Knowledge of structural design at undergraduate level of study.

Syllabus of lectures:

1) Current state of knowledge about fire design of structures, simplified approach vs. advanced modeling

2) Verification and validation of models, testing of structures.

3) Fire design of concrete structures, method for slender columns

4) Experimental analysis of heat transport in concrete structures

5) Numerical analysis of heat transport in concrete structures, influence of humidity)

6) Modeling fire and heat transport in software, practical examples, concrete structures after a fire

7) Modeling explosion, structural response and reconstruction

8) Fire design of steel and steel concrete. construction in European standards, cross-sections of the 4th class, material, heat transfer, models

9) Steel-concrete ceiling structures, principle, tests, advanced models, simple models

10) Charring of wood, principles and assumptions, design of light wooden structures for the effects of fire

11) Numerical simulation of a fire experiment of a composite wood-fiber concrete ceiling

12) Research and trends in the field of wooden structures during fire

13) Robustness of structures and connectors, column failure, connector failure, WTC collapse, consequence classes, collapse models

Syllabus of tutorials:

1) Assignment, explanation of the exercise principle and time schedule, division into work groups

2) Preparation of samples in laboratories of steel and wooden and concrete and masonry structures

3) Demonstration of gas temperature measurement, thermocouples + plate temperature sensors

4) Test of prepared samples

5) Test of prepared samples

6) Test of prepared samples

7) Evaluation of temperature measurements from the laboratory

8) Fire and heat transport modeling in software

9) Validation of fire modeling and heat transport in software

10) Modeling of heat transport by steel and wooden sample in software

11) Validation of modeling of heat transfer to steel and wood samples in the software

12) Verification of experimental data, preparation of the presentation

13) Presentation of work results by groups
