Preface to the second edition

Since the publication of the First Edition of this book, substantial progress

has occurred in Structural Fire Safety Engineering which has necessitated

the production of a Second Edition. However, the author must report

the death of two personally influential figures noted in the acknowledgements

to the first edition, namely Bill Malhotra and Tony Morris, and the

retirement of the third, Bob Anchor.

The intention behind this text remains provision to those involved in

aspects of the design of structures to withstand the accidental effects due

to fire occurring within part or the whole of the structure and of the

tools required to enable such a design to be carried out. One of the major

revisions is that the author has concentrated on the European Design

Codes rather than British Standards which will in the course of the next

five years become effectively obsolete. However, the designer should still

be aware that any design code is subject to revision or amendment and

that it is essential that the most recent edition be used, and that where

this produces a discrepancy between this text and the Code, the Code

must be taken as the final arbiter.

The second major revision has been due to the impact of the largescale

fire tests carried out at Cardington. This has meant there has had

to be a re-assessment of the behaviour of composite steel–concrete frame

structures, in that the whole structure performance markedly outweighs

that of single elements. Equally, there are a number of guides produced

by either the Institution of Structural Engineers or the Building Research

Establishment promoting Structural Fire Safety Engineering.

The best available texts were used for the EuroCode material as some

of the EuroCodes had not at the time when this text was prepared been

finally approved or released by CEN (Comité Européen de Normalisation)

for publication by the appropriate National Standards Organization. It is

thus possible that there might be discrepancies between this text and the

final published EN versions of the EuroCodes. It is hoped such variations

are slight and will mostly be concerned with interpretive matters or

notation and not basic principles.
