ABSTRACT

Small-diameter round timber is a kind of by-product mainly from the thinning operation of the plantations. It is plentiful and inexpensive, and is generally destined for non-structural applications. The small-diameter round timber is rarely used as structural members. This study was aimed to provide an innovative but simple way to use the small-diameter round timber as structural members. Three kinds of composite members were developed to be used in light frame wood construction, i.e. the built-up studs, the wood-steel joists and the wood-steel roof trusses. The shearwalls and diaphragms made of the developed composite members were also examined. To facilitate the fabrication, the configurations of these members were described in details. Efforts were also made to investigate the structural performances of these members via full-scale tests. It was found that the developed composite members could be used as substitutes of dimension lumber in the framework of light frame construction. The developed members could be also pre-fabricated as standard components in a mill and assembled on site. As a result, application of small-diameter round timber as structural members developed would be an efficient way to increase use of forest resource from plantation and lower the construction cost of light frame buildings.

小直径圆材在轻型框架结构中的应用

摘要

小径圆材是一种主要来自人工林间伐作业的副产品。它数量丰富且价格低廉,通常用于非结构应用。小直径圆木很少用作结构构件。本研究旨在提供一种创新但简单的方法来使用小直径圆木作为结构构件。三种复合构件被开发用于轻型框架木结构,即组合螺柱、木钢托梁和木钢屋架。还检查了由开发的复合构件制成的剪力墙和隔板。为了便于制造,详细描述了这些构件的配置。还努力通过全面测试来研究这些构件的结构性能。研究发现,开发的复合构件可以在轻型框架结构中用作规格材的替代品。开发的成员也可以作为标准部件在工厂中预制并在现场组装。因此,应用小直径圆材作为结构构件的开发将是增加人工林资源利用和降低轻型框架建筑建造成本的有效途径。
