Scope of EN 1990

(1)P EN 1990 applies to the design of buildings and civil engineering works in timber (solid timber, sawn, planed or in pole form, glued laminated timber or wood-based structural products e.g. LVL) or wood-based panels jointed together with adhesives or mechanical fasteners. It complies with the principles and requirements for the safety and serviceability of structures, and the basis of design and verification that are given in EN 1990:2002.

(2)P EN 1990 is only concerned with requirements for mechanical resistance, serviceability, durability and fire resistance of timber structures. Other requirements, e.g concerning thermal or sound insulation, are not considered.

(3) EN 1990 is intended to be used in conjunction with:

EN 1990:2002 Eurocode - Basis of structural design

EN 1991 "Actions on structures"

EN´s for construction products relevant to timber structures

EN 1998 "Design of structures for earthquake resistance", when timber structures are built in seismic regions

(4) EN 1990 is subdivided into various parts:

EN 1995-1 General

EN 1995-2 Bridges

(5) EN 1995-1 "General" comprises:

EN 1995-1-1 General - Common rules and rules for buildings

EN 1995-1-2 General - Structural Fire Design

Scope of EN 1995-2

(1) EN 1995-2 gives general design rules for the structural parts of bridges, i.e. structural members of importance for the reliability of the whole bridge or major parts of it, made of timber or other wood-based materials, either singly or compositely with concrete, steel or other materials.

(2) The following subjects are dealt with in EN 1995-2:

Section 1: General

Section 2: Basis of design

Section 3: Material properties

Section 4: Durability

Section 5: Basis of structural analysis

Section 6: Ultimate limit states

Section 7: Serviceability limit states

Section 8: Connections

Section 9: Structural detailing and control

(3) Section 1 and Section 2 also provide additional clauses to those given in EN 1990:2002 "Eurocode: Basis of structural design".

(4) Unless specifically stated, EN 1995-1-1 applies.
