1.1 Scope of EN 1995-1-1

(1) EN 1995-1-1 gives general design rules for timber structures.

(2) EN 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) It is assumed that the requirements for execution given in EN 1995-3 are complied with. 

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 (all parts) to ensure that what is built meets the requirements for mechanical resistance, serviceability, durability, and fire performance.

(2) This document gives guidance on moisture control during transport to the building site, storage on site, handling on site and erection.

(3) This document gives guidance on workmanship and deviation limits during execution.

(4) This document assumes that there is 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) parts which are not designed according to EN 1995;

b) temporary works (such as formwork, scaffolding, propping, shoring, etc.);

c) specification, production and conformity of timber members in accordance with European technical product specifications;

d) deviation limits for other properties than mechanical resistance, serviceability, durability and fire performance;

e) contractual aspects, responsibilities of the various parties, competency requirements or the degree of independence of the personnel undertaking the inspection; f) health and safety requirements during execution.

1.2 Assumptions

(1) It is assumed that all relevant provisions of EN 1995 are complied with.

(2) It is recognized in this document that areas such as detailed requirements for competence of personnel, and details related to Quality Management are within the competence of the CEN Member States.

(3) Before the execution begins on a part of the structure, it is assumed that the following are available on site:

— the drawings and specification of that part;

— the execution specification.

(4) Before the start of the execution, it is assumed that the execution specification has been checked for completeness.

(5) It is assumed that previous work (such as foundations) has been inspected and that 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 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 Scope of EN 1995-2

(1) This document gives 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) Prestressed timber-concrete composite (TCC) members are not covered by this document. The design of stress-laminated timber decks used as part of a TCC system is covered.

(3) Systems which rely on friction between wood and concrete are not covered by this document.

1.2 Assumptions

(1) The assumptions of EN 1990‑1 apply to this document.

(2) It is assumed that the requirements for execution given in EN 1995‑3 are complied with.
