“…There have been many studies on the bearing properties of timber 1)2) . On the other hand, though studies on the bearing capacity of wood-based panels include Sekino et al's study on particle board 3) and Ogawa et al's study on the bearing capacity of plywood 4) , there are only a few studies that have comprehensively examined the parameters and considered how the various conditions affect the bearing properties and how the degree of influence varies depending on the type of panels. The underlying mechanism of fracture remains elusive, which represents a crucial foundation for the development of theoretical equations for determining characteristic values.…”

Bearing property is important for the design of the connection. There are few studies about the bearing property of the wood-based panels. First, the tensile bearing test of the wood-based panels Plywood and OSB of strong and weak axial specification, was conducted based on the comprehensive parameters. Test parameters were set as dowel insertion position, size of pilot hole and dowel diameter. The correlation between parameters and the mechanical characteristics: failure behavior, ductility, yield stress and maximum stress, was verified. To verify how much each parameter effect on maximum stress, standardized multiple regression analysis was conducted. These results provide insights into the failure behavior and stress distribution, supporting certain assumptions: (1) PW and OSB is deformed dominantly in-plane and out-of-plane respectively; (2) the relative stress spread range is decreased with the larger diameter of the dowel; (3) the stress spread range is widened by load step; and (4) the bearing stress is spread vertically and horizontally in strong and weak specification respectively, also verified in this section. A detailed investigation was performed using DIC and CT scanning techniques to shed light on the stress distribution and fracture processes. Three load steps were configured and subjected to cyclic loading. Verification and comparison were carried out for each specification, layer, and step, providing a clearer understanding of the stress distribution and fracture processes. These results are consistent with the conclusions drawn from the comprehensive testing.
