Abstract :
[en] The information that is necessary to perform the fire design of a structure made of a particular material, say a steel structure, is:
a) The bases of design, stated in EN 1990.
b) The mechanical actions, i.e. the forces, acting on the structure in the fire situation. Some information is found in EN 1991-1-2, but explicit reference is also made to EN 1991-1-1 that is therefore also necessary.
c) The thermal actions, i.e. the fire and the heat flux induced in the elements by the fire. The information is in EN 1991-1-2.
d) The rules for determining the temperatures in the structure during the course of the fire. They are given in the fire part of the relevant material eurocode, e.g. EN 1993-1-2 for a steel structure.
e) The rules for determining the structural stability. They are given in the fire part of the relevant material Eurocode, e.g. EN 1993-1-2 for a steel structure, but reference is often made to the cold part of the same material Eurocode, EN 1993-1-1 for a steel structure.
This layout is valid in general but some exceptions do exist: the structural stability of timber elements, for example, does not necessarily require the determination of the temperatures in the element and step d) may be omitted; the same holds if the fire resistance is determined from tabulated data, for concrete elements for example.
The rest of this book is organised according to this layout, see Fig. 1-2:
Chapter 2 deals with bases of design and mechanical loads.
Chapter 3 deals with thermal attack from the fire.
Chapter 4 deals with thermal analysis by simple calculation model.
Chapter 5 deals with mechanical analysis by simple calculation model.
Chapter 6 deals with the design of joints.
Chapter 7 deals with thermal and mechanical analysis by the advanced calculation model.
Chapter 8 gives four design examples showing how a complete and sometimes complex structure can be designed using the concept of element or substructure analysis.
