| Resumen: | 1.1 Scope of EN 1995-1-2
(1) This document deals with the design of timber structures for the accidental situation of fire exposure and it is intended to be used in conjunction with EN 1995-1-1 and EN 1991-1-2.
This document only identifies differences from, or supplements to, normal temperature design.
(2) This document applies to timber 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 EN 1995-1-1 and are designed accordingly.
(5) The methods given in this document are applicable to all products covered by European technical product specifications made reference to in this document.
1.2 Assumptions
(1) In addition to the general assumptions of EN 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. 1.1 Anwendungsbereich von EN 1995 1 2 (1) Dieses Dokument regelt Bemessung und Konstruktion von Holzbauwerken für die außergewöhnliche Situation einer Brandbeanspruchung und ist in Verbindung mit EN 1995 1 1 und EN 1991 1 2 anwendbar. Dieses Dokument bestimmt nur Unterschiede von oder Ergänzungen zur Bemessung unter Normaltemperatur. (2) Dieses Dokument ist anwendbar für Holzbaukonstruktionen, die eine tragende Funktion, raumabschließende Funktion oder beides erfüllen. (3) Dieses Dokument enthält Grundsätze und Anwendungsregeln für die Bemessung von Tragwerken mit festgelegten Anforderungen hinsichtlich der vorgenannten Funktionen und Anforderungsklassen. (4) Dieses Dokument ist anwendbar für Tragwerke oder Teile von Tragwerken, die in den Anwendungsbereich von EN 1995 1 1 fallen und entsprechend bemessen werden. (5) Die in diesem Dokument enthaltenen Verfahren sind auf alle Produkte anwendbar, auf deren Europäische Technische Produktspezifikationen in diesem Dokument verwiesen wird. 1.2 Voraussetzungen (1) Die folgenden Voraussetzungen sind zusätzlich zu den allgemeinen Voraussetzungen nach EN 1990 anwendbar: die Wahl des maßgebenden Bemessungsbrandszenarios wird durch entsprechend qualifiziertes und erfahrenes Personal getroffen oder durch die maßgebende nationale Vorschrift vorgegeben; jede bei der Bemessung berücksichtigte Brandschutzmaßnahme wird ausreichend gewartet. 1.1 Domaine d'application de l'EN 1995-1-2 (1) Le présent document traite du calcul des structures en bois pour une situation accidentelle d'exposition au feu et doit être utilisé conjointement avec l'EN 1995-1-1 et l’EN 1991-1-2. Le présent document identifie uniquement les différences avec le calcul à température normale, ou lui apporte des compléments. (2) Le présent document s'applique aux structures en bois devant remplir une fonction porteuse, une fonction séparative ou les deux. (3) Le présent document donne les principes et les règles d'application relatifs au calcul des structures par rapport aux exigences spécifiées eu égard aux fonctions mentionnées ci-dessus et aux niveaux de performances. (4) Le présent document s'applique aux structures, ou aux parties de structures, relevant du domaine d'application de l'EN 1995-1-1 et conçues en conséquence. (5) Les méthodes données dans le présent document sont applicables pour tous les produits couverts par les spécifications techniques produits européennes qui sont référencées dans le présent document. 1.2 Hypothèses (1) Outre les hypothèses de travail générales définies dans l'EN 1990, les hypothèses suivantes s'appliquent : - le choix du scénario de feu de calcul pertinent est fait par un concepteur possédant une qualification et une expérience appropriées, ou est indiqué par la réglementation nationale concernée ; - les mesures de protection contre l'incendie prises en compte dans le calcul font l'objet d'un entretien approprié. |

Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
