Whereas traditionally the verification of fire safety is based on prescriptive measures and criteria, an evolution toward performance-based design can be noticed, which is reflected in the design approaches given in the fire parts of Eurocodes 1 and 2. In Part 1-2 of Eurocode 11, general design aspects of structures exposed to fire are given as well as specific load combinations, design values of thermal and mechanical material properties, fire models, and heat transfer models. Most of these design principles are applicable to all types of construction materials. In Part 1-2 of Eurocode 22, specific approaches related to concrete structures are given, i.e., models giving the influence of high temperatures on material characteristics, a method based on tabulated values, simplified verification methods, and the basic principles of advanced calculation methods. In this paper, a review is presented of the most relevant clauses of the mentioned documents. For practical applications, the complete documents should be consulted.
