交叉层压木材（CLT）板被用作结构隔膜元件，在大木结构建筑中形成主要的抗侧力系统。为了更好地了解CLT隔板的整体性能，进行了单调和循环面内剪切板对板样条连接试验。花键连接使用不同间距的钉子和螺钉构建。测试程序的实验结果可以从弹性刚度、强度和延性方面对连接系统的性能进行表征。根据该特定测试程序的结果，钉花键连接在刚度和强度方面表现出相似的性能，并且比螺钉连接的延展性高出58.7%，这在一定程度上可以解释为螺钉连接观察到的更大的超强度因素。提出了一种简化的性能模型，以帮助设计人员确定所测试的各种样条连接的弹性、非弹性和峰值后力参数。
Cross-laminated timber (CLT) panels have been used as structural diaphragm elements that form the primary lateral force-resisting system in mass-timber buildings. To better understand the overall performance of CLT diaphragms, an experimental program including monotonic and cyclic in-plane shear panel-to-panel spline connections tests was conducted. The spline connections were constructed using nails and screws with different spacings. Experimental results from the testing program allow for characterization of the performance of the connection systems in terms of elastic stiffness, strength, and ductility. Based on the results of this specific testing program, nailed spline connections displayed similar performance in terms of stiffness and strength and were more 58.7% more ductile than the screw connections, which is partly explained by the larger overstrength factors observed for the screw connections. A simplified performance model is presented to aid designers in determining the elastic, inelastic, and post-peak force parameters of the various spline connections tested.
