Comparison of Evaluation Results of Nailed Joints in Shear Properties Obtained from Two Methods
Keywords:Nailed joint, Shear property, Evaluating method, Monte-Carlo method
AbstractShear properties of nailed joints must be evaluated to understand the mechanical property of structural elements using nailed joints. Numerous studies regarding this evaluation exist. However, the testing methods differ between the studies. Thus, clarification of the difference in the evaluated results of the testing methods becomes important. Therefore, this study aims to clarify this difference by conducting shear tests on nailed-joint specimens. This study adopts two methods, which are described in ASTM International and Japanese Agricultural Standard, respectively. The evaluated results of the tests are compared. The comparison clarifies that there is no difference in the average values of the characteristics. Meanwhile, a difference is observed in the variance. In addition, this study discusses the reasons for this difference. The author posits a hypothesis that the difference in variance is due to the difference in the number of nails in the joint specimens and presents the validity of this hypothesis with an analysis using the Monte-Carlo method.
