CEN/TC 250/SC 5 - Eurocode 5: Design of timber structures

1.1   Scope of CEN/TS 19103
(1)   CEN/TS 19103 gives general design rules for timber-concrete composite structures.
(2)   It provides requirements for materials, design parameters, connections, detailing and execution for timber-concrete composite structures. Recommendations for environmental parameters (temperature and moisture content), design methods and test methods are given in the Annexes.
(3)   It includes rules common to many types of timber-concrete composite, but does not include details for the design of glued timber-concrete composites, nor for bridges.
NOTE   For the design of glued timber-concrete composites or bridges alternative references are available.
(4)   It covers the design of timber-concrete composite structures in both quasi-constant and variable environmental conditions. For ease of use, it provides simple design rules for quasi-constant environmental conditions and more complex rules for variable environmental conditions.
1.2   Assumptions
(1)   The general assumptions of EN 1990 apply.
(2)   CEN/TS 19103 is intended to be used in conjunction with EN 1990, EN 1991 (all parts), EN  1992 (all parts), EN  1994 (all parts), EN 1995 (all parts), EN 1998 (all parts) when timber structures are built in seismic regions, and ENs for construction products relevant to timber structures.

General rules for the structural design of buildings and civil engineering works made of timber and/or wood-based panels, either singly or compositely with concrete, steel or other materials. Detailed rules for structural design of buildings.

Supplementary to Part 1-1. Additional and varied rules to be used for the design of timber structures which are required to avoid premature structural collapse and to limit the spread of fire in the accidental situation of exposure to fire.

General rules for the structural design of buildings and civil engineering works made of timber and/or wood-based panels, either singly or compositely with concrete, steel or other materials. Detailed rules for structural design of buildings.

(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.

1.1   Scope of prEN 1995-1-1
(1) prEN 1995-1-1 gives general design rules for timber structures.
(2) prEN 1995-1-1 also gives specific design rules for buildings and timber civil engineering works.
1.2   Assumptions
(1) The assumptions of EN 1990 apply to this document.
(2) prEN 1995-1-1 is intended to be used in conjunction with EN 1990, EN 1991 (all parts), EN 1998 (all parts) when timber structures are built in seismic regions.

1.1   Scope of EN 1995 3
(1) This document gives minimum requirements for execution of timber structures (buildings and bridges) designed in accordance with EN 1995 to ensure that what is built meets the requirements for mechanical resistance, serviceability, durability and fire performance.
(2) This document includes the minimum requirements for moisture control during transport to building site, storage on site, handling on site and execution.
(3) This document gives guidance on workmanship and permitted geometrical deviations during execution.
(4) This document relies on an execution specification which states all the specific requirements relevant for the execution of a particular structure.
(5) For products covered by a European technical product specification, this document only covers those aspects of fabrication such as cutting, machining and drilling after placement of the product on the market.
(6) This document does not cover:
a)   Design and detailing rules;
b)   Secondary members which are not designed according to EN 1995;
c)   Temporary works (such as formwork, scaffolding, propping, shoring, etc.);
d)   Specification, production and conformity of timber members in accordance with European technical product specifications;
e)   Permitted geometrical deviations required for appearance, thermal or sound insulation;
f)   Contractual aspects, responsibilities of the various parties, competency requirements or the degree of independence of the personnel undertaking the inspection;
g)   Health and safety requirements during execution.
1.2   Assumptions
(1) It is recognized in this document that areas such as detailed requirements for competence of personnel, and details related to the Quality Management are within the competence of the CEN Member States.
(2) Before the execution begins on a part of the structure, it is assumed the following are available on site for inspection levels IL2-B and IL3 (Inspection Level according to EN 1990 and Table 4.1 of this document):
-   the design of that part, including calculations, drawings, and specification;
-   the execution specification.
(3) Before the start of the execution, it is assumed that the execution specification has been checked for completeness.
(4) It is assumed that previous work (such as foundations) has been inspected and any work which needs to be done due to deviations from the execution specification has been carried out.

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 prEN 1995 1 1 and prEN 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 prEN 1995 1 1 and are designed accordingly.
(5) The methods given in this document are applicable to all products covered by harmonized technical 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) 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.
