EN 1995-1-1 General – Common rules and rules for buildings
EN 1995-1-2 General rules – Structural Fire Design
The standard does not cover the design of structures subject to prolonged exposure to temperatures over 65°C.
Eurocode 5 covers:
Basis of design
Basis of structural design
Ultimate limit states
Serviceability limit states
Connections with metal fasteners
Components and assemblies
Structural detailing and control
Designing with EN 1995 (Eurocode 5)
Eurocode 5 is based on a limit state philosophy as opposed to the permissible stress approach previously used in national Codes of Practice for timber design.
The limit state system starts with characteristic values of materials to which the designer applies factors to take account of safety, load duration, environmental conditions etc. This is in contrast to the permissible stress approach where the published values already had safety factors applied. As a consequence, characteristic values are higher than permissible stress values.
It can be used in conjunction with the following standards:
EN 1990: 2002 Eurocode – Basis of design
EN 1991 Eurocode 1: actions on structures
EN 1998 Eurocode 8: for building in seismic regions
ENs for construction products relevant to timber structures (for example. EN 636 (plywood), EN 300 (OSB) & EN 14373 (LVL).
National Annex NA (informative) to EN 1995-1-1: 2004 + A1 : 2008, Eurocode 5 : Design of timber structures – Part 1-1 ; General – Common rules and rules for buildings
This gives alternative procedures, values and recommendations with notes indicating where national choices have been made. These values are known as Nationally Determined Parameters and are only for use with the geographical bounds of a specific member state.
