中置木剪力墙被认为是木框架结构较好的抗侧力体系。其中一个重要原因是双剪钉（DSN）连接具有良好的抗侧性能。在这项研究中，8组标本进行了单调的横向荷载下，调查不同的变量对DSN连接的横向性能的影响。考虑了实际中层板木剪力墙的代表性变量，包括覆板厚度、钉距和加载方向。试验结果表明，钢板连接的破坏模式取决于钢板厚度和钉距。钉距和护套厚度的增加可以显著提高极限承载力和延性，而对初始刚度影响不大。此外，加载方向对云杉-松树-冷杉（SPF）框架的DSN连接的极限强度和初始刚度有显着的影响。最后，将试验数据理想化，通过典型的指数函数模型来解释DSN连接的荷载-位移行为。这项研究可以用来开发基准数据的有限元DSN连接模型，以预测性能的中层木剪力墙。
Midply wood shear wall is regarded as a preferable lateral resistance system for timber frame structures. One of the most important reasons is attributed to the good lateral performance of double-shear-nail (DSN) connections. In this study, eight groups of specimens were tested under monotonic lateral loads to investigate the influence of different variables on the lateral performance of the DSN connections. Representative variables derived from practical midply wood shear walls were considered, including sheathing thickness, nail edge-distance and loading direction to the grain of framing. Test results indicate that the failure modes of the DSN connections depend on sheathing thickness and nail edge-distance. The increase of nail edge-distance and sheathing thickness can significantly improve the ultimate strength and the ductility, while it had little influence on the initial stiffness. Moreover, loading direction to the grain of spruce–pine–fir (SPF) framing had significant influences on the ultimate strength and initial stiffness of DSN connections. Finally, the testing data was idealized to translate the load–displacement behavior of the DSN connections through a typical exponential function model. This study can be used to develop baseline data for the finite-element DSN connection model to predict the performance of midply wood shear walls.
