This guide provides engineers with an overview of the structural fire engineering design process and the techniques available to ensure the safe and economical fire design of concrete structures. It is the result of a collaborative research project funded by the UK government and the concrete industry. It will be of particular value to structural engineers familiar with the ambient temperature design of concrete structures but unfamiliar with the process of structural fire engineering design. It will also be of interest to regulators and specialist fire engineering consultants. It covers aspects of the performance of concrete in fire; comparison of UK standards for the design of concrete structures in fire with European standards (EN 1992-1-1 and EN 1992-1-2); and numerical analysis and simulation procedures for concrete structures in fire.
