“…It is interesting to see how the cracks are formed on the end cross section of the bottom rail with regard to pith orientation and washer size. The crack shapes found here are quite similar to those noted in Caprolu et al (2014) for single-sided sheathing.…”

“…The results of the different tests are summarised in Tables 5 and 6. In a previous study by Caprolu et al (2014), the pith orientation turned out to be an important parameter at the evaluation of the test results. The failure load is presented with respect to this parameter in Table 5 (pith upwards) and Table 6 (pith downwards).…”

“…This failure mode is directly linked to the distance between the nails in the sheathing-to-framing joint. In Caprolu et al (2014), two experimental studies were presented, where this distance was set as 25 and 50 mm, respectively. In this study, the distance was chosen as 50 mm since it is a more realistic distance to use in practice.…”

In partially anchored shear walls, the leading stud is not fully anchored against the uplift; hence the uplifting force is resisted by the sheathing-to-framing joint along the bottom rail. These joint forces will introduce crosswise bending and shear in the bottom rail leading to possible splitting failures. To design partially anchored shear walls, plastic design methods can be used and, therefore, the bottom rails must not fail in a brittle manner. In this paper, results of two experimental programmes with respect to the splitting capacity of bottom rails with double-sided sheathing due to uplift in partially anchored shear walls are presented. This was evaluated varying the distance between the washer edge and the edge of the bottom rail, and the pith orientation of the bottom rail. The experimental results show two brittle failure modes for the bottom rail: (1) a crack opening from the bottom surface of the bottom rail and (2) a crack opening from the edge surface of the bottom rail. The results indicate that the distance from the edge of the washer to the edges of the bottom rail has a decisive influence on the load-carrying capacity and failure modes of the bottom rail.
