本文介绍了竹胶合板桁架的试验和分析研究，这是一种不同于传统的钢或木材的新型结构材料。在竖向荷载逐渐增大的情况下，对两种结构尺寸的六个足尺桁架模型进行了破坏试验。模型桁架的破坏是由上弦受压弦杆的侧向屈曲引起的。试验结果表明，该模型胶合板桁架具有足够的刚度和强度。分析了桁架在铰接、刚接和半刚接等不同节点条件下的受力性能。在设计荷载水平下的变形分析结果与使用各种类型的节点模型的试验结果吻合良好。半刚性节点模型提供了一个稍微好一点的预测模型桁架的承载能力。然而，分析桁架模型的基础上铰接节点通常提供保守的预测承载能力。
This paper presents experimental and analytical studies on trusses made of glue-laminated bamboo or glubam, which is a new type of structural material unlike conventional steel or timber. Six full-scale model trusses with two types of configurations and sizes were tested to failure under gradually increased vertical load. The failure of the model trusses was caused by lateral buckling of the top compressive chords. Tests show that the model glubam trusses have adequate stiffness and strength. Analyses were also conducted to model the truss behavior with considering different joint conditions, such as pinned, rigid as well as semi-rigid joint using fictitious members. The analytical results for deformation at the design load level agree with the test results favorably well using all types of joint models. The semi-rigid joint model provides a slightly better prediction to the load carrying capacities of the model trusses. However, the analytical truss model based on pinned joints generally provides conservative prediction to load carrying capacities.
