Pine wood with an annual ring width of 1-5 mm, without destructive defects and decay, was selected to manufacture wooden elements for all connections. The production of test samples was carried out according to applicable standards (DBN B.2.6-161:2017, Eurocode 5:2004; NDS:2018). The manufactured samples are shown in Fig. 2.
