Description

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.

Course Structure

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.

Who is the target audience?
  • 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

As a Structural Engineer with more than 15 years’ experience in building industry I am currently teaching how to use Eurocodes as the most advanced building design codes on a world scale. I am teaching also how to use technology for solving daily engineering calculations, including software development as a support to structural engineering.

I have been working on project documentation for all types of building structures, reinforcement plans for RC structures, fabrication plans of steel structures, fire resistance calculation of building structures including consultation on the most appropriate fire protection. Based on years of experience and participation in post-earthquake reconstruction, I specialize in Earthquake Reconstruction and rehabilitation of buildings too.

I have all possible licenses for the design and revision of project documentation for building structures at Slovenian Chamber of Engineers. Kindly check my licence at the address Slovenian Chamber of Engineers.

I run a company for structural engineering in Slovenia / EU and I have also additional license for the revision of the project documentation for building structures.
