摘要
对竹集成材和竹指接集成材的物理力学性能进行了试验研究,并与几种常用的建筑结构木材(如落叶松Larix gmeini,水曲柳Fraxinus mandshurica,杉木Cunninghamia lanceolata),毛竹Phyllostachys pubescens及多孔砖砌体、混凝土物理力学性能相比。结果表明:竹集成材的抗拉强度和抗压强度较高,抗剪强度表现良好的塑性性能,是一种综合力学性能很好的建筑结构材料,其产品不仅可在梁、板、柱等常见建筑结构中使用,也适于工字梁、桁架等复杂结构用材;竹指接集成材受指接的影响,其抗拉强度、抗压强度和抗剪强度低于竹集成材,但已能满足一般承重类的结构材料使用。
The physical and mechanical parameters of glued laminated bamboo wood was obtained by test research for providing a useful guidelines in safe design and construction. Besides, by comparing with those of other materials such as Larix g meini, Fraxinus mandshurica, Cunningharnia lanceolata, Phyllostachys pubescens, fired perforated brick and concrete, conclusions could be made that glued laminated bamboo wood was a kind of material with excellent physical and mechanical performances including comparatively higher ultimate tensile and compressive strength and better plastic performance in shear resistance, etc. So, glued laminated bamboo wood could be used as column or beam not only in common structures but also in complicated ones such as tress and I-beam. The study also showed that glued laminated bamboo wood with finger joint, with lower value of mechanical parameters than glued laminated bamboo wood, could still be used as a common load-carrying building material.
