II SPECIAL CONDITIONS OF THE EUROPEAN TECHNICAL APPROVAL

1 Definition of product and intended use Definition of the product Sima stanchion holders type B150, B100, B2-100, B2-200, S350, S450, BH-160, UHB2, type U (40, 70 and 90 mm) and type BH-165 are welded steel connectors (post bases). The upper part e.g. a plate or a U-shaped plate is fastened to the timber member with nails, screws, bolts or dowels. The lower part of the post base is either a bar, a threaded rod, a tube or a plate for embedment into the support of concrete or a steel plate to be fastened by anchor bolts to the support of concrete. The post bases are made from pre-galvanized steel Grade S 235 JRG2 according to EN 10025 with a corrosion protection of hot dipped galvanized according to EN ISO 1461 with a zinc coating thickness of approximately 55 µm. In addition, the stanchion holders can be delivered with electroplated zinc corrosion protection made from 12µm Fe/Zn 12c. Steel quality, dimensions of the post bases and hole positions are shown in Annex A. Intended use The intended use of the post bases is to support timber structures or wood-based structural members to their support, where requirements for mechanical resistance and stability and safety in use in the sense of the Essential Requirements 1 and 4 of Council Directive 89/106/EEC shall be fulfilled. Each connection shall be made with one post base. The static and kinematic behaviour of the timber members or the supports shall be as described in Annex B. The wood members can be of solid timber, glued laminated timber and similar glued members, or wood-based structural members with a characteristic density from 290 kg/m3 to 420 kg/m3. Depending on the fastening in the wood there are different demands for the wood material. For nailing in the side of the wood members the requirement to the material of the wood members can be fulfilled by using the following materials:

• Solid timber classified to C18-C40 according to EN 338 / EN 14081

• Glued members of timber classified to C18-C40 according to EN 338 / EN 14081 when structural adhesives are used.

• Glued laminated timber classified to GL24c or better according to EN 1194 / EN 14080.

Annex B states the load-carrying capacities of the post base connections for a characteristic density of the timber for at least 320 kg/m3. The load-carrying capacity of the connections for a lower characteristic density should be determined under the assumption that the load-carrying capacity is proportional to the density. The concrete strength class is assumed to be C15 unless otherwise indicated in Annex B. The design of the connections shall be in accordance with Eurocode 5 or a similar national Timber code. The post bases are intended for use for connections subjected to static or quasi static loading. The post bases with a electroplated zinc coating 12µm Fe/Zn 12c are intended for use in service class 1 and 2 according to EN 1995 (Eurocode 5). The post bases which are hot dipped galvanized according to EN ISO 1461 with a zinc coating thickness of approximately 55 µm are intended for use in service class 1, 2 and 3 according to EN 1995 (Eurocode 5). It is assumed that the force acting on the post base is an upward or downward force F1 acting in the centre of the post base Assumed working life The assumed intended working life of the Angle Brackets for the intended use is 50 years, provided that they are subject to appropriate use and maintenance. The information on the working life should not be regarded as a guarantee provided by the manufacturer or ETA-Danmark A/S. An “assumed intended working life” means that it is expected that, when this working life has elapsed, the real working life may be, in normal use conditions, considerably longer without major degradation affecting the essential requirements.

*) See page 5 of this ETA **) In accordance with http://europa.eu.int-/comm/enterprise/construction/internal/dangsub/dangmain.htm In addition to the specific clauses relating to dangerous substances contained in this European Technical Approval, there may be other requirements applicable to the products falling within its scope (e.g. transposed European legislation and national laws, regulations and administrative provisions). In order to meet the provisions of the EU Construction Products Directive, these requirements need also to be complied with, when and where they apply.


Safety principles and partial factors The characteristic load-carrying capacities have been calculated without considering different ratios between the partial factors for timber connections and steel cross sections. Therefore, in the end use calculation based on this ETA, this shall be considered. The values in annex B have been determined by multiplying the calculated resistance of the connection by kmod to consider load duration and service classes in accordance with EC 5. Additionally, the capacities indicated for the upward force F1 takes into account the national partial safety factor γM. 2.1 Mechanical resistance and stability See annex B for characteristic load-carrying capacity in the direction F1.. The characteristic capacities of the post bases are determined by calculation as described in the EOTA Guideline 015 clause 5.1.2. They should be used for designs in accordance with Eurocode 5 or a similar national Timber Code. Connector nails in accordance to national approval The load bearing capacities of the post bases has been determined based on the use of NKT connector nails 4,0 x 40 mm and 4,0 × 60 mm in accordance with the Danish national approval for the nails. The characteristic withdrawal capacity of the nails has been determined by testing in accordance with EN 1382: Timber structures - Test methods - Withdrawal capacity of timber fasteners: For electroplated zinc covered nails No performance has been determined in relation to ductility of a joint under cyclic testing. The contribution to the performance of structures in seismic zones, therefore, has not been assessed. No performance has been determined in relation to the joint’s stiffness properties - to be used for the analysis of the serviceability limit state.

2.7 Related aspects of serviceability 2.7.1 Corrosion protection in service class 1 and 2. In accordance with ETAG 015the post bases having a zinc coating 12µm Fe/Zn 12c fulfill the requirements. 2.7.1 Corrosion protection in service class 1, 2 and 3. In accordance with ETAG 015 the post bases which are hot dipped galvanized according to EN ISO 1461 with a zinc coating thickness of approximately 55µm fulfill the requirements.

Annex B Characteristic load-carrying capacity

Design Basis - general

The design values Fd are calculated from the modified characteristic capacities FR,k for service class 1 and 2 and the indicated load-duration classes as:

M

kRd

FF

γ,=

with the material partial coefficient γM for wood. The characteristic load-carrying capacities have been modified by the factor kmod as given in Table 1.

Table 1 Factor kmod

Load duration class P L M S I

Permanent Long term Medium term Short term Instantaneous 0,6 0,7 0,8 0,9 1,1

The modified characteristic capacities stated in this Annex B The capacities are valid for service class 1 and 2.

For Service class 3 the characteristic capacities may on the safe side be found by multiplication by 0,78.

Density The load-carrying capacities of the post base connections are stated for a timber strength class C18 with a characteristic density of 320 kg/m3. The load-carrying capacity of the connections for a lower characteristic density should be determined under the assumption that the load-carrying capacity is proportional to the density. The load-carrying capacity for a larger characteristic density shall unless a special investigation is made be taken as that of this document. Concrete The load-carrying capacities of the post base connections are stated for a concrete class C15 unless otherwise indicated. Wane Where force is carried by contact compression no wane may occur. Fastening Unless otherwise indicated the calculations the holes in the post bases have to be fully applied with the applicable fasteners. The fastener types for which the calculations have been made are stated at each post base. Assumed characteristic capacities of anchor bolts The characteristic capacities that have been assumed for the bolt connection to the support are stated at each post base. For smaller capacity than stated of the bolt connection the capacity of the post base is reduced proportionally.


The capacities in the tables are stated in kN and kNm. Acting forces Unless otherwise indicated in the tables with load-carrying capacities, the forces are assumed to act as described below: F1 Load-carrying capacity for upward or downward load acting along the central axis of the joint.

The direction of the force is indicated in the following tables as compression (downward) of tension (upward) where relevant

Combined forces In the following tables the load-carrying capacities are given for the individual loads: F1 for compression and tension For combinations of loads it is – unless otherwise indicated sufficient to verify that the individual loads can be taken.
