落叶松锯材目测分级与力学性能相关性的研究

Study on Correlation of Visual Grading for Larch Lumber and Mechancial Properites

以落叶松锯材为试验对象,依据GB50005-2003《木结构设计规范》中外观分等的相关规则,对人工林落叶松锯材进行了以节子为检量对象的外观分等试验,并对分等后的锯材进行了弯曲破坏试验,分析比较了外观分等结果与其弯曲破坏检测结果的相关关系。

This study takes the plantation Larch lumber for visual grading focusing on the knots based on the relevant rules of visual grading in Chinese GBS0005 - 2003 （（Code for Design of Timber Structures）. In the process of visual grading, bending failure test was carried out, and the correlation between visual grading results and bending failure test results were analysed and compared.
