Technical Provisions

1. Technical description of the product

Kijk en Bouw nv produces timber frame building kits for

residential and non-residential buildings. The kid includes

external walls, internal walls, shared walls, floors and roofs.

All details of essential construction elements are given in

Annex I.

The timber frame building kits are prepared in the factory for

each individual building. Normally, the timber parts of

loadbearing constructions are prefabricated so that only

minor cutting and shaping is needed at the building site.

The mean loadbearing construction of the building is made of

a timber frame that may contain additional load-bearing

components (e.g. joists or steel girders for concentrated

loads) which, according to its structural analysis, are required

for each individual construction works.

Detailed information about the assembly of the different parts

is given in Annex II.

Material specifications are given in Annex III.

This European Technical Assessment refers to a timber frame

building kit. Complementary parts such as external claddings,

foundations, basements, metallic structural parts, surface

coverings, stairs, internal fittings, windows and doors,

technical installations of water, heating, ventilation and

electricity as well as other components necessary to form

completed works are not covered by this assessment,

although they are generally in the standard design and

delivered by Kijk en Bouw nv.

Although the external cladding is not part of the kit, it may be

delivered by Kijk en Bouw nv and it is also possible that some

types of external claddings are installed in the factory.

The kits according to this ETA may be delivered throughout

Europe. Adjustments depending on national regulations,

regulations from other authorities, special demands from

customers or specific climate conditions for the individual

building may be necessary in certain cases and are then

described in the design documentation for each individual

work.

2. Specification of the intended use(s) in

accordance with the applicable EAD (ETAG

007)

2.1 Intended use

The intended use for the building kits are residential buildings.

The building kits may also be used for non-residential

constructions as far as the required performance is met.

The intended use shall be evaluated in each individual case

depending on the climatic boundary conditions, assuming

the kit satisfies the climatic conditions for zone A, B, C and

moderate climate according to EOTA Guidance document

003 “Assessment of working life of products”

Adjustments depending on national regulations, regulations

from other authorities, special demands from customers or

specific climate conditions for the individual building may be

necessary in certain cases and are then described in the

design documentation for each individual work.

2.2 Substructure

This European Technical Assessment does not comprise the

substructure of the building

A plan drawing with the dimensions and the schematic

details of the substructure are delivered by the ETA-holder.

The substructure shall be individually designed according to

the local building regulations to correspond to the building

site.

A waterproof membrane shall be installed between the

substructure and the wood-based components according to

the construction details.

2.3 Working life and durability

The provisions made in this European Technical Assessment

are based on an assumed working life of at least 50 years3 for

the loadbearing structure and for non-accessible

components and materials and 25 years for repairable or

replaceable components and materials like claddings,

roofing materials, exterior trims and integrated components

like windows and doors, provided that the building kit is

subjected to appropriate use and maintenance.

Indications given regarding the working life cannot be

interpreted as a guarantee given by the producer or the

UBAtc, but are to be regarded only as a means for choosing

the appropriate product(s) in relation to the expected

economically reasonable working life of the construction

works.

All production of the components of the kit is performed in

dry, heated industrial halls. The materials being included in the

kits are stored indoors under favourable conditions.

The design of the timber frame building kit ensures that

deterioration of materials and components during the

assumed intended working life does not significantly affect

the performance of the kit in relation to fulfilling all the

essential requirements.

In function of the durability class of the timber components

and the intended use, the timber components can be

treated against timber-boring insects, fungus and blue stain.

The external finishes are not assessed in the framework of this

ETA. The systems shall comply with the relevant technical

specifications.

The metal fasteners and other structural connections are

either inherently corrosion resistant or are protected against

corrosion according to EN 1995-1-1/A1.

2.4 Design

The production of the components for the timber frame

building kits shall be done on the basis of a design made for

each individual delivery.

3 This means that it is expected that when the working life has

elapsed, the real working life may be, in normal use

conditions, considerably longer without major degradation

affecting the essential requirements of the works. The

indications given as to the working life of a building cannot

be interpreted as a guarantee given by the producer or the

Technical Assessment Body. They should only be regarded as

a means for the specifiers to choose the appropriate criteria

for building kits in relation to the expected, economically

reasonable working life of the works.

ETA 13/0277 - 4/38

The design process shall comply with the building regulations

applicable in the Member State in which the building is to be

erected and normally takes into account the following:

Requirements for structural design;

Fire safety requirements;

Special local requirements related to health and the

environment;

Safety in use requirements

Noise protection requirements;

Energy saving requirements.

The stiffness of the suspended floor structures is calculated

according to EN 1995-1-1/A1. The loadbearing capacities in

Annex I consider a maximal deflection of L/300 and L/500.

Suspended floors have sufficient stiffness to avoid

unacceptable vibrations from normal use.

2.5 Execution of the construction works

The manufacturer’s instructions regarding transport and

storage shall be followed.

The components and materials shall be protected against

harmful wetting during transport and storage.

The components shall not be lifted or stored in such a way

that they will be damaged e.g. because of local stresses due

to dead load or excessive bending deformation.

The components of the kit are packed to avoid damages

during the storage and transportation.

Before the installation it shall be controlled that the

components of the building kit are not damaged during

transport or storage. Damaged components and materials

shall be replaced by sound ones.

If there is a need to moodily or repair the construction this

may be done if allowed for in the installation plans. In any

case, modifications are allowed only by written consent by

the manufacturer of the kit.

The kits are erected according to the relevant description in

Annex 2. The ETA-holder provides a general manual for the

installation covering:

Erection systems and equipment;

Permanent anchoring to foundations;

Temporary bracings;

The height of the wall is 2600 mm. The tabulated value is a design value which is a result of a load combination. Only vertical

loads are considered in the load combination. The load combination can be computed as:

qD = 1,35 x qg,k + 1,50 x qQ,k,1 + 1,50 x ( i>1 0,i x qQ,k,I )

where qg,k is the characteristic value of the permanent load, qQ,k,i are the characteristic values of the variable loads and 0,i

the factor for combination of variable loads. The variable loads are considered to be medium term.

The design value is calculated for service class 2. Other configurations are possible and will be calculated by the

manufacturer.

Vertical design resistance for short term loading

The following table shows the vertical design resistance for the wall in combination with a short term horizontal loading. The

horizontal loading in the table is a result of a load combination. There are two possibilities:

qH = 1,5 x w (1)

qH = 1,5 x 0 x w (2)

where w is the characteristic value of the horizontal loading (for example wind). The vertical design resistance is a result of a

complementary load combination for the vertical loading :

qD = 1,35 x qg,k + 1,50 x ( i>1 0,i x qQ,k,I ) (1)

qD = 1,35 x qg,k + 1,50 x qQ,k,1 + 1,50 x ( i>1 0,i x qQ,k,I ) (2)

The result without horizontal loading is given for qH = 0 kN/m. In that case, one of the variable loads must be short term.

OSB3 – 9 mm – nails 2,4 mm x 45 mm – s = 150 mm 2,74

The racking resistance in the table is for a fully vertically anchored wall. The anchorage can be obtained by a tie down or by

dead load. When the anchorage is only partial, the racking resistance is lower. In that case, the manufacturer can give

corrected values in function of the design of the kit.

The values in the table assume structural sheeting at one side of the wall. If the structural sheeting is placed on both sides of

the wall, then:

if both materials are the same: double the values in the table above;

if plate material is different: add the values for both plate materials given in the table, but take only 75

% into account for the weakest plate material - if fasteners have similar slip moduli. In the other case,

take only 50 % of the weakest plate material.

Other configurations are possible and will be calculated by the manufacturer.
