ETA-07/05, issued on -0- II SPECIFIC PART OF THE EUROPEAN TECHNICAL ASSESSMENT 1 Technical description of product and intended use Technical description of the product The SIMSPON Strong-Tie Concealed Beam Hangers are three dimensional nailing plates made of pre-galvanized steel Grade S 2 GD + Z275 according to EN 3 or stainless steel 1.01 and 1.04 according to EN 0 or a stainless steel with a minimum characteristic yield stress of 235 N/mm² or a minimum ultimate tensile strength of 3 N/mm². or aluminium AlMgSi 0,7 according to DIN The range addressed by this Approval consists of various hangers which have in common the necessity to practice a notch and holes in the joist for the dowels path : TU, TUB, TUS, TUBS, ETNM, BTN, BT4, BT, BTC, BTALU, CBH, Janebofamily. They are intended for wood-wood connections and wood-concrete connections with angles varying from to 90. The geometry and standard dimensions are given in Annexes D. ETB and ETS connectors are two-piece non-welded, face-fixed connectors to be used in timber to timber connections. ICS and ICST are two-piece non-welded elementconnectors to be used in timber to timber connections. EL connectors are one-piece non-welded, face-fixed connectors to be used in timber to timber connections as well as connections between a timber joist and a concrete structure or a steel member. ELS connectors are one-piece non-welded, face-fixed connectors to be used in timber to timber connections. The connectors are made from aluminium grade EN AW-2 T6 according to EN with minimum yield strength of 2 MPa, a minimum tensile strength of 295 MPa and a minimum ultimate strain of %. Dimensions, hole positions and aluminium type are shown in Annex D6 to D. Typical installations are shown in Annex C. 2 Specification of the intended use in accordance with the applicable EAD The intended use of the SIMPSON Strong-Tie Concealed Beam Hangers is to establish connections of joists with rectangular cross sections to their support, where requirements for mechanical resistance and stability and safety in use in the sense of the Basic Works Requirements 1 and 4 of Regulation (EU) 5/11 shall be fulfilled. The joist may be either of solid sawn or Engineering Wood Product listed in Annex C1 This support may be either a solid sawn element, an Engineering Wood Product listed in Annex C1, or concrete. With regard to moisture behaviour of the support and/or joist, the use is possible in service classes 1 and 2 defined in EN :04 for the Concealed Beam Hangers made out of galvanised steel. The use is possible in service class 1, 2 and 3 defined in EN :04 for Concealed Beam Hangers made out of stainless steel 1.01 and 1.04 according to EN 0, or another stainless steel as described before in structures subject to internal or external atmospheric exposure (including industrial and marine environment), or exposure in permanently damp internal conditions, if no particular aggressive conditions exist. Such particular aggressive conditions are e.g. permanent, alternating immersion in seawater or the splash zone of seawater, chloride atmosphere of indoor swimming pools or atmosphere with extreme chemical pollution (e.g. in desulphurization plants or road tunnels where de-icing materials are used). A concealed joist hanger produced from steel, which is resistant for these atmospheres, may be used in these areas. The scope of the connectors regarding resistance to corrosion shall be defined according to national provisions that apply at the installation site considering environmental conditions. They are not intended to be used in areas where they might support seismic actions. They are supposed to be used with specified fasteners mentioned in Annex C3 and according to fastening combinations and nail patterns given in Annexes B. The ETB, ETS, EL and EL-S connectors are intended for use in making end-grain to side-grain connections in load bearing timber structures, as a connection between a timber joist and a solid timber or wood based header, where requirements for mechanical resistance and stability and safety in use in the sense of the Basic Works Requirements 1 and 4 of Regulation (EU) 5/11 shall be fulfilled. The EL connectors are also intended for use in making an end-grain connection between a timber joist and a concrete structure or a steel member. The provisions made in this European Technical Assessment are based on an assumed intended working life of the connectors of years. The indications given on the working life cannot be interpreted as a guarantee given by the producer or Assessment Body, but are to be regarded only as a means for choosing the right products in relation to the expected economically reasonable working life of the works.

ETA-07/05, issued on Mechanical resistance and stability See annex D for characteristic load-carrying capacities of the SIMPSON Strong-Tie Concealed Beam Hangers and SIMPSON Strong-Tie Joist End connectors. The mechanical capacities of the concealed beam hangers and Joist End connectors are determined by calculation assisted by testing as described in the EOTA Guideline 015 clause They should be used for designs in accordance with EN (Eurocode 5) or a similar national timber code. The load-bearing capacities given in Annexes D of the concealed beam hangers and Joist End connectors have been determined based on the use of connector nails or 4.0 x in accordance to ETA-04/0013 and screws are described in Annex C3. It is allowed to use connector screws or connector nails 4.0 x or 4.2 x or 4.2 x in accordance to ETA-04/0013. Case by case calculations have to be carried out to determine the loadbearing capacity of the connection. The design also allows the use of threaded nails in accordance to EN 592 with a diameter in the range mm and a minimum length of 35 mm, assuming a thick steel plate when calculating the lateral nail loadbearing capacity. If no calculations are made a reduction factor equal to the ratio between the characteristic withdrawal capacity of the actual used threaded nail and the characteristic withdrawal capacity of the corresponding connector nail according to table B1 in ETA-04/0013 is applicable for all load-bearing capacities of the connection. 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 3. Aspects related to the performance of the product serviceability when used in timber structures using the timber species described in Eurocode 5 and subject to the conditions defined by service class 1 and 2 Serviceability of the Concealed Beam Hangers is understood as their ability to resist loads without unacceptable deformations General aspects related to the fitness for use of the product Concealed Beam Hangers and Joist End connectors are manufactured in accordance with the provisions of this European Technical Assessment using the manufacturing processes as identified in the inspection of the plant by the notified inspection body and laid down in the technical documentation.

ETA-07/05, issued on -0- Force direction F4 Additional information: - The BTALU can be used with CNA nails in diameter Ø4 mm with a length from 35 to 0mm and CSA screws of a diameter of Ø5 mm and a length from 35 to mm. Capacity of these fasteners can be found in ETA-04/ The load is located on the centre of gravity of the dowels - The dowels must be distributed homogeneously on the whole height of the hanger. - The nails must be distributed homogeneously all around the dowels - For solid timber: The spacing and edge distance to the timber must respect rules given by EUROCODE 5 (EN Table.5) - For CLT: the spacing and edge distance to the timber must respect rules from ETA of the CLT manufacturer. - The minimum distance between the edge of the hangers and the dowels is equal to 1,5 d (d is the diameter of the dowels) - All dowels must have the same diameter, length and yield capacity.
