嵌固强度是设计栓钉式木结构横向受力节点时最常用的一个参数。然而，这种性质对于任何给定的木材标本都不是唯一的，而是取决于几个因素。目前，缺乏将一些主要因素作为一个整体加以考虑的文献。在这篇评论中，试图把这些因素放在一起，然后在历史测试结果的背景下检查它们。其次是新的测试结果，来自理想化的测试应用于设计双面冲压金属板紧固接头。结果表明，在组合的因素的变化可能会导致明显的差异，从测试中获得的嵌入强度的值。通过考虑一些关键因素的定量影响，可以解释理论上获得的嵌入强度值与理想化测试结果之间的差异。此外，通过理论计算与理想化试验结果的相关性，验证了所提出的获得穿孔金属板木材节点有效嵌入强度的间接方法。
Embedding strength is a key parameter most commonly adopted for designing laterally loaded timber joints fastened with dowel-type fasteners. This property, however, is non-unique for any given specimen of timber but is dependent upon several factors. Currently, there is a scarcity of literature that considers some of the major factors as a whole. In this review, an attempt is made to bring some of these factors together and then examine them in the context of historical test results. This is followed by new test results derived from idealized tests for application in designing double-sided punched metal plate fastened joints. It is shown that changes in combinations of factors can potentially lead to appreciable differences in the values of embedding strength obtained from tests. By accounting for the quantitative effect of some key factors, it is possible to explain differences between theoretically obtained embedding strength values and idealized test results. In addition, the proposed indirect method of obtaining effective embedding strengths for punched metal plate timber joints is validated through correlation of idealized test results with theoretical calculations.
