1.1 Scope of prEN 1996 3 (1) The scope of EN 1996-1-1 applies also to this this document. (2) This document provides simplified calculation methods to facilitate the design of the following unreinforced masonry walls, subject to certain conditions of application: - walls subjected to vertical and wind loads; - walls subjected to concentrated loads; - shear walls; - basement walls subjected to lateral earth pressure and vertical loads; - walls subjected to lateral loads but not subjected to vertical loads. NOTE For those types of masonry structures or parts of structures not covered by (2), the design can be based on EN 1996-1-1. (3) The rules given in this document are consistent with those given in EN 1996-1-1, but are more conservative in respect of the conditions and limitations of their use. (4) The rules given in this document assume that concrete floors are designed according to EN 1992 1 1. (5) This document applies only to those masonry structures, or parts thereof, that are described in EN 1996-1-1 and EN 1996-2. (6) The simplified calculation methods given in this document do not cover the design of double-leaf walls. (7) The simplified calculation methods given in this document do not cover the design for accidental situations. 1.2 Assumptions (1) The assumptions of EN 1990 apply to this document.

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.

This standard gives the general basis for the design of structures in plain, reinforced and prestressed concrete made with normal weight, lightweight and heavyweight aggregates together with specific rules for buildings, bridges and civil engineering structures, including temporary structures, under temperature conditions between –40 °C and +100 °C generally. It 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 Basis of structural and geotechnical design. EN 1992 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. This Part 1-1 does not cover: − resistance to fire (see EN 1992-1-2), − fastenings in concrete (see EN 1992-4), − seismic design (see EN 1998), − particular aspects of special types of civil engineering works (such as dams, pressure vessels), − design with galvanised reinforcing steel, − structures made with no-fines concrete, aerated or cellular concrete, lightweight aggregate concrete with open structure components, − structures containing structural steel sections (see EN 1994 for composite steel-concrete structures), − Structural parts made of concrete with D_lower < 8 mm, unless otherwise stated in the code.
