落叶松规格材的钉连接性能

Nailed Joint Performance of Larch Dimensional Lumber

钉连接是木结构中常用的连接方式之一。依据美国钉连接的试验方法及设计值的确定方法,对我国东北地区落叶松的钉连接性能进行了检测。结果表明,随着圆钉直径的增大,落叶松的抗拔出力和抗剪切力基本呈上升趋势。并对东北地区落叶松钉连接的参考设计值进行了分析。

The nail joint is a common connection used in timber structures.This paper focuses on nailed joint performance of larch lumber,a common species in northeast China.The authors introduced the test methods for American nailed joints and how to develop the design values for wood structures with domestic wood species. The results could be used to develop design values of larch in this area.
