Eurocode 2 - Design of concrete structures - Part 1-2: Structural fire design

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.
