摘　　要：选择国产常用齿板及北美二级SPF规格材,依照GB/T 50329-2012《木结构试验方法标准》,在荷载平行于木纹及齿板主轴的条件下,测试50、100及150mm三种宽度齿板连接抗滑移承载力和板齿承载力。结果表明,齿板连接抗滑移承载力和板齿承载力无明显尺寸效应,100mm宽度齿板连接的抗滑移承载力和板齿承载力变异最小。According to the National Standard GB/T 50329-2012 for test methods of timber structures under forces parallel to grain and longitudinal direction of metal plate connectors,metalplate connectors with three different widths（50,100 and 150 mm）were selected to join SPF Ⅱdimensional lumber from North America.Then lateral slip resistance and ultimate lateral resistance of the metal-plate connectors were evaluated.Testing results showed that the metal plates with 50～150 mm in width had little influence on the lateral slip resistance and the ultimate lateral resistance.But the metal plate with 100 mm in width showed the most stable bearing capacity.
