| 摘 要： | 介绍正交胶合木滚动剪切性能测试方法,分析和比较不同标准中测试方法的优缺点,并总结CLT滚动剪切性能影响因素及其研究进展,以期能为国内CLT材料研究提供参考。结果表明,测试方法尚未统一,不同测试方法、材料种类、锯材宏观构造特征、CLT加工工艺和产品几何构造对滚动剪切性能影响较大。建议针对目前概括的主要因素进行深入研究,建立统一的测试标准,同时应基于国产木材、结构复合板材和国内木结构行业实际情况展开CLT研究和应用。

| Abstract: | This paper mainly introduced the rolling shear properity test method of cross-laminated timber (CLT),analyzed and compared the advantages and disadvantages of the test methods in different standards,and summarized the influencing factors and research progress of CLT rolling shear properties to provide reference for domestic CLT material research.From the research results at home and abroad,the test methods had not been unified.Different test methods,material types,macrostructure characteristics of sawn timber,CLT processing technology and product geometry had great influence on rolling shear properties.It was recommended to conduct in-depth research on the main factors currently summarized,to establish a unified test standard,and to develop CLT research and application based on the actual situation of domestic wood,structural composite board and domestic wood structure industry. |
