- Аннотация: This study is devoted to one of the most common types of wooden structuralelements joints - nailed connections. The article presents the results of experimentalstudies of two types nailed connections on metal plates: traditional connectionswithout bushings and connections, reinforced (modified) with pressed-in fiberglassbushings. The methods of mathematical planning of the experiment were used duringthe test. That allowed to significantly reduce the number of tested samples ofconnections and to obtain mathematical dependences in the form of responsefunctions for such characteristics as breaking load Nt and load NI-II, corresponding tothe upper boundary of the elastic behavior area of the compound from three factors:the angle between the direction of the acting force and the direction of the woodfibers, the dowel diameter and the wall thickness of the fiberglass bushing. Theobtained dependences allow us to evaluate the values of the loads Nt and NI-II for thenailed connections with bushings without testing.According to the experimentplanning matrix, 15 types (series) of connections with pressed-in fiberglass bushingsand 9 types (series) of traditional nailed connections without bushings weretested.
