Introduction Wood is one of the main materials in modern construction (Diza Lestari (2018); Thelanderson and Larsen; Anshari et al. (2017); Roos et al. (2010); Homon et al. (2024); Ghasemi et al. (2026)). In recent years, wood has become even more widely used (Petric (2013); Rudavska et al. (2020); Subramanian (2010); Shams Huq et al. (2025); Wang et al. (2025); Zakic (1974); Zhao et al. (2020). Wooden elements and structures are used in the construction of residential, sports, industrial, and public buildings and structures (Lamichhane et al. (2025); Ivaniuk et al. (2025); Omotayo et al. (2024); Datsiuk et al. (2024); Betts et al. (2010); Bula and Pelekh (2023)). They can compete with other materials and in many cases they prevail (Abed et al. (2022); Alberktas et al. (2020); Landis at al. (2002); Heidarzadeh et al. (2026); Rescalvo et al. (2020); Hua et al. (2025)). The connections of wood between itself and with other materials are diverse (Sroka et al. (2025); Köhler et al. (2007); Correal et al. (2014); Mykhailovskyi (2022); Bukhanevych et al. (2025); Homon et al. (2025)). One of the most common is nail joints (Aleksiievets et al. (2024); Girhammar et al. (1988)). Such connections are subjected to various loads and influences, and can also operate under different temperature and humidity conditions (Huang et al. (2006); Roshchuk et al. (2024); Han and Tesfamariam (2025); Pavluk et al. (2025); Gomon et al. (2024); Matviiuk et al. (2025)). Very often, wooden elements and structures operate under low-cycle loads, including nail joints. Abstract A methodology for experimental studies of nail joints of wooden structural elements under low-cycle loads and the features of manufacturing experimental samples are proposed. The results of experiments conducted under such operating conditions are presented. Based on the results of the studies, deformation diagrams of nail joints of wooden structural elements under low-cycle loads are constructed. The bearing capacity of nail joints depending on the limit deformations is established.
