- By the end of the course you will be able to calculate standard fire resistance of steel structural elements
- Must have the following standards EN 1990, EN 1991-1-2, EN 1993-1-1, EN 1993-1-2
- Must have knowledge of how to design steel structures to EN 1993-1-1
Fire resistance of building structure« means the ability of the structure exposed to fire the appropriate time maintaining its strength. To recognize the precise value of the duration in which the construction retains its capacity, is crucial for fire-resistant design. Fire analysis calculation takes into account the actual technical state of construction material exposed to thermal impact or fire load and provide you with the critical temperature, e.g. the temperature to which the structure maintains its capacity or advice you of the optimal fire protection of the structural elements.
Why must we learn Fire Analysis?
Because we do not want that we have fire protection, which is oversized and as well uneconomical. On the other hand we do not want that the construction is in fire risk and does not allow a safe evacuation, as well as fire extinguishing and rescue.
In this course, I will present a thorough overview of structural fire analysis according to nominal temperature-time curves according to Eurocodes.
We will learn the following topics:
- What is thermal action?
- How to calculate temperature of protected and unprotected steel sections
- How to create load combinations for the fire limit states
- How to calculate fire resistance of structural members and their critical temperature
- Fire protection systems for steel structures
All chapters will also provide you with worked examples which will cover theoretical part presented. At the end you will be presented a calculation of critical temperature and required fire protection for typical structural elements of real structure.
I will provide you with an easy-to-follow material explanation, each section is clearly demonstrated in the presentation and covered with worked examples.
- Course is intended for students, structural engineers, professionals who want to learn how to calculate standard fire resistance of steel structural elements according to Eurocodes
In this lesson we will learn what is thermal action and how we consider the fire action on the structure. It will be clearly described what kind of nominal temperature-time curves are covered in Eurocodes and how they can be applied to structure.
In this lesson we will learn how to calculate the increase in temperature in unprotected steel element according to Eurocodes. Numerical procedure for this calculation will be clearly presented, including detailed description of all parameters and worked example.
In this lesson we will learn how to calculate the increase in temperature in protected steel element according to Eurocodes. Numerical procedure for this calculation will be clearly presented, including detailed description of all parameters and their limitations. Additionally worked example will be calculated.
In this lesson we will learn how to define fire load combination and which safety factors can be used for particular load case. We will learn general rule and simplified rule for calculating effects of actions for fire load combination. Additionally worked example will be presented.
In this lesson we will repeat cross section classification from designing steel structures at room temperature and describe what is different in cross section classification at elevated temperature. Additionally worked examples will be presented for all four classes of cross sections.
In this lesson we will learn the calculation of the reduced design moment resistance of a member with classes 1,2,3 at elevated temperature for combined bending and shear acting together . Non-uniform temperature distribution will be explained too. Additionally worked example will be calculated.
In this lesson we will analyse the results of calculation. We will compare the results of fire analysis with default value of critical temperature which is usually used in many countries without knowing the exact value of the critical temperature for typical structural elements. Finally we will learn why it is so important to know the exact value of the critical temperature for optimal and safe fire design.
