Abstract
Introduction. One of the promising types of joints in wooden structures is the joint using glued steel washers. However, the use of adhesive compounds is, for a number of reasons, characterized by lower manufacturability as compared to a threaded connection. Given the relevance of developing new technological types of joints in structures, it is necessary to study the threaded washer connection of wooden elements without the use of adhesives.
Aim. To study the performance of a threaded washer connection by conducting a full-scale experiment of specimens exhibiting different parameters of threaded washers in order to assess the prospects for further study of the joint in question and its implementation in construction practice.
Materials and methods. The procedure for studying the joint under consideration involves making a series of specimens and conducting an experiment to determine the failure loads and ultimate strains, followed by the visual inspection of these specimens after failure.
Results. The experimental study of twelve specimens (four series of specimens exhibiting different parameters of threaded washers, with three specimens in each) yielded failure loads, and graphs showing their deformation were constructed. The performance of the joint in question was examined; its advantages and disadvantages in terms of bearing capacity, manufacturability, and reliability were identified.
Conclusions. Threaded washer joints in wooden structures are characterized by high bearing capacity and manufacturability. In spite of such a disadvantage as the effect of wood moisture on the strength and reliability of this joint, its advantages make it promising for further study and use in construction practice.
