| The aim of this course is to give students an understanding of the design methods of structures at accidental situations, fire and explosion.
The course is focussed on all design methods involved in fire design: prediction of fire scenario, evaluation of fire load, calculation of gas temperatures in the fire compartment and structural analysis. Special attention is paid to fire modelling when several design models is presented including nominal temperature curves, simple models and advanced models.
Gas temperature in the fire compartment is considered as basis for the structural design. Methods for prediction of temperature of the structural elements are presented and mechanical properties of structural materials (steel, concrete, timber and aluminium structures) are presented. Design models for steel, concrete, steel concrete composite, timber and aluminium structural elements loaded by tension, compression and bending moment are presented. Attention is paid to protection of steel and timber structures to fire, various methods of protection are described.
Smaller part of the course is focussed on explosions. Types of explosions are described together with design models. Basic principles of structural analysis are presented. Design methods are explained with focus to increase robustness of the structure.
The theoretical part is supplemented with practical exercises using simple design models with aim to apply the knowledge in design of simple structural elements. Understanding of basic principles of structural analysis and design of steel, concrete and timber structures is necessary.

The course is conceived in order to give students following skills:
- To understand the basic methods in fire engineering.
- To be able to develop possible fire scenarios and to understand various fire models.
- To predict the gas temperature in the fire compartment for the selected fire scenarios, to evaluate the fire load density and other fire parameters necessary for thermal analysis of the fire compartment.
- To be able to predict temperature of unprotected and protected structural elements and to be able to select / design suitable fire protection of those elements.
- To understand the specific problems related to structural analysis at fire. To be able to predict the mechanical load at fire and calculate internal forces of simple structures exposed to fire.
- To understand the effect of high temperature on mechanical properties of steel, concrete, timber and aluminium alloys. To be able to design steel, concrete, steel-concrete composite, timber and aluminium structures exposed to fire.
- To understand the purpose of fire testing, measurements and equipment of fire testing laboratory, large scale testing.
- To understand the models for load by explosion in open and closed space, structural analysis at explosion, structural damages and repair of structures.
- To understand the robustness of structures and to be able to design simple structures to ensure structural integrity.
