In some cases the asymmetrical laying of connectors is needed (Sg HT ≠ Sg NT ). (2) The compression design strength of the connector is the lower between • Characteristic values comply with the EN 1995:2014 standard in accordance with ETA-11/0030. the withdrawal-side design strength (R 1 V,d), the instability design strength (R 2 V,d) and the tensile design strength (R3 V,d). RV,d = min R1V,k kmod γM R2V,k γM1 R3V,k γM2 • For the mechanical resistance values and the geometry of the screws, reference was made to ETA-11/0030. • For the calculation process a mass density equal to ρk = 550 kg/m3 has been considered for hardwood (oak) elements. • Dimensioning and verification of the timber elements must be carried out separately. The coefficients γM and kmod should be taken according to the current regulations used for the calculation. (3) The assembly height (m) applies in the event of symmetrical installation of the flush connectors (Sg HT = Sg NT ) above the elements. (4) The thread axial resistance to withdrawal has been evaluated considering an effective thread length equal to Sg. The connectors must be inserted at 45° with respect to the shear plane.
