摘要
针对影响结构用规格材力学性质的主要因素,从样本数、含水率效应、尺寸效应、测试方法、强度性质之间的关系等对国外的研究进展进行了概述,并结合我国研究现状,对我国未来结构用规格材力学性质的研究提出建议。开展结构用规格材强度基础性质的研究,能够为制定规格材强度性质的静态测试标准及评价技术体系提供理论依据,对推广结构用规格材在建筑结构方面的应用、提高其附加值具有重要意义。
In view of the main factors influencing the mechanical properties of dimension lumber, the overseas research progress is stated in terms of the relationship between the number of samples, size effect, testing method and strength properties. Based on the research status in China, some suggestions for the research development of mechanical properties of dimension lumber in China are put forward. The research of basic strength properties of dimension lumber can provide theoretical basis for establishing the standards for the static tests of the strength properties of dimension lumber and evaluation technology systems, of great importance for popularizing the application of dimension lumber in architectural structure and improving the added value of dimension lumber.
