1.1 Scope of FprEN 1992-1-1 (1) This document gives the general basis for the design of structures in plain, reinforced and prestressed concrete made with normal weight, lightweight and heavyweight aggregates. It gives specific rules for buildings, bridges and civil engineering structures, including temporary structures; additional requirements specific to bridges are given in Annex K. The rules are valid under temperature conditions between −40 °C and +100 °C generally. This document complies with the principles and requirements for the safety, serviceability, durability and robustness of structures, the basis of their design and verification that are given in EN 1990. (2) This document is only concerned with the requirements for resistance, serviceability, durability, robustness and fire resistance of concrete structures. Other requirements, e.g. concerning thermal or sound insulation, are not considered. (3) This document does not cover: - resistance to fire (see EN 1992 1 2); - fastenings in concrete (see EN 1992 4); - seismic design (see EN 1998 (all parts)); - particular aspects of special types of civil engineering works (such as dams, pressure vessels); - structures made with no-fines concrete, aerated or cellular concrete, lightweight aggregate concrete with open structure components; - structures containing steel sections considered in design (see EN 1994 (all parts)) for composite steel and concrete structures; - structural parts made of concrete with a smallest value of the upper sieve aggregate size Dlower < 8 mm (or if known Dmax < 8 mm) unless otherwise stated in this Eurocode. 1.2 Assumptions (1) The assumptions of EN 1990 apply to FprEN 1992-1-1. (2) It is assumed that the requirements for execution and workmanship given in EN 13670 are complied with.

1.1 Scope of prEN 1992 1 2 (1) This document deals with the design of concrete structures for the accidental situation of fire exposure and is intended to be used in conjunction with prEN 1992 1 1 and EN 1991 1 2. This document identifies differences from, or supplements to, normal temperature design. (2) This document applies to concrete structures required to fulfil a loadbearing function, separating function or both. (3) This document gives principles and application rules for the design of structures for specified requirements in respect of the aforementioned functions and the levels of performance. (4) This document applies to structures, or parts of structures, that are within the scope of prEN 1992 1 1 and are designed accordingly. (5) The methods given in this document are applicable to normal weight concrete up to strength class C100/115 and lightweight concrete up to strength class LC50/60. 1.2 Assumptions (1) In addition to the general assumptions of prEN 1990 the following assumptions apply: - the choice of the relevant design fire scenario is made by appropriate qualified and experienced personnel or is given by the relevant national regulation; - any fire protection measure taken into account in the design will be adequately maintained.
