MAINSECONDARY JOINT The wide choice of connection systems are applicable to many dierent design demands: joints between timber elements must ensure static resistance and reliability under fire conditions, while providing an optimal aesthetic result.

STATIC SAFETY

The main-to-secondary joist connection in timber structures can be schematized as a hinge. This type of joint restrains the element translation but not its rotation, dierently from the encastre (fixed end) that is usually found in concrete structures. Hinge nodes can transfer shear force and axial force from secondary to main joist but cannot bear bending moment or torsion.

The connection system is not a punctual joint, as it is realized through the interaction of more elements. The geometry of the connection creates, along with the shear transfer, an extra parasitic bending moment. Consequently, additional stress generates on the elements (tension on the fasteners and compression on the primary beam).

The load bearing capacity values are certified (CE marking), computable (according to ETA) and refined by rothoblaas based on the designer needs (technical documentation).

Depending on connector typology, dierent values of load bearing capacity are obtained according to the loading direction: FV = shear load directed towards the bottom FUP = shear load directed towards the top FLAT = lateral shear load FAX = axial load (tension)

AESTHETIC REQUIREMENTS

FIRE PROTECTION

Timber structures properly designed ensure high performance also under fire circumstances.

Everyone sees what you appear to be, few experience what you really are. [N. Machiavelli]

The metallic connection is adequately protected and isolated by the surrounding timber. Hence there is no strength reduction and it maintains its mechanical properties unaltered for the required amount of time.(es. R45 = 45 minutes)

The metallic connection is directly exposed to fire and has very limited load bearing capacity (usually R15 = 15 minutes). Furthermore the reduction of the timber section due to carbonization, results in a reduction of the fastener penetration depth.

Timber is a slow-burning combustible material. Under fire conditions there is a reduction of the cross section, with the portion not aected by carbonization that remains ecient.

At high temperatures, metallic materials experience drastic deterioration of their mechanical properties.

The fasteners are placed entirely inside the timber elements to provide an optimal aesthetic result.

The metal fasteners are placed on the surface of the timber element, thus being visible and with a high aesthetic impact.

NOTES TIMBER TO TIMBER

(1) Self-drilling dowels WS 7 (fu,k = 550 N/mm2).(2) Smooth dowels STA 12 (fu,k = 360 N/mm2).(3) Partial nailing should be realized alternating the holes (see p. 26). Partial nailing is necessary for joist-column connections in order to observe minimum fastener spacings; it can be applied also for joist-joist connections.(4) Strength values listed in the table have been evaluated for an angle = 30% (16,7) of the secondary joist to the vertical and by considering a precut AluMIDI hidden bracket. To optimize timber element dimensions and joint strength it is possible to cut the AluMIDI bracket at an angle starting from the AluMIDI2200 model.

Coecients m and kmod must be taken according to the current Standard adopted for the design. Admissible values are obtained according to DIN 1052:1988. For the calculation process a timber density k = 380 kg/m3 and a concrete

grade C 25/30 have been considered. Dimensioning and verification of the timber elements must be carried out

separately. In some cases the connection shear strength RV,k is notably large and may be

higher than the secondary joist strength. Particular attention should be paid to the shear check of the reduced timber crossection in correspondence with the bracket location

Strength values of the connection system are valid for the calculation hypotheses listed in the table. For dierent paterns the free software myProject is available (www.rothoblaas.com)

(1) Smooth dowels STA 16 (fu,k = 470 N/mm2). (2) Partial nailing of the column should be realized alternating the holes (see p. 26). Partial nailing is necessary for joist-column connections in order to observe minimum fastener spacings; it can be applied also for joist-joist connections.(3) The anchor disposition on concrete is obtained by placing the fasteners alternately according to the reference picture, depending on the type of anchor selected (see p. 26).(4) Chemical anchor VINYLPRO with threaded rods (type INA) of minimum strength grade equal to 5.8. with hef = 128 mm.

INSTALLATION

* For thicker plates it is necessary to realize a countersink in the lower part of the steel plate.

For VGS screw-lengths > 300 mm a 5 predrill is recommended.The assembly must be performed so as to guarantee that the stress is evenly distributed among all the installed VGU washers.


Charatteristic values consistent with EN 1995:2008 and in accordante with ETA-11/0030.

Admissible values are obtained according to DIN 1052:1988. For the calculation process a timber density of k = 380 kg/m3

has been considered. The fastener pull-out strength has been evaluated by considering a

45 angle to the grain and an eective length of the threaded part equal to Sg.

(1) The design shear strength of the joint is the minimum among the timber design shear strength (RV,d) and the steel design shear strength (Rtens,d 45).

For the correct realization of the joint, the fastener head should be fully embedded into the VGU washer. For intermediate values of SPLATE linear interpolation is allowed. Dimensioning and verification of timber elements and steel plates shall be carried out separately.

NOTES

Characteristic values are consistent with EN 1995:2008 and in accordance with ETA. Design values can be obtained from characteristic values as follows:

Coecients m and kmod must be taken according to the current Standard adopted for the design. For the calculations, a timber density k = 350 kg/m3 has been considered. Dimensioning and verification of the timber elements must be carried out

separately. For combined loading the following verification shall be satisfied:


(1) Strength values are valid even when the UV anti pull-out screw is inserted. The main beam dimensions should be checked prior to the connection installation.(2) Strength values are referred to a joint where the load is centered with respect to the secondary beam depth.
