Glulam bamboo has been preliminarily explored for use as a structural building material, and its stress–strain model under axial loading has a fundamental role in the analysis of bamboo components. To study the tension and compression behaviour of glulam bamboo, the bamboo scrimber and laminated bamboo as two kinds of typical glulam bamboo materials were tested under axial loading. Their mechanical behaviour and failure modes were investigated. The results showed that the bamboo scrimber and laminated bamboo have similar failure modes. For tensile failure, bamboo fibres were ruptured with sawtooth failure surfaces shown as brittle failure; for compression failure, the two modes of compression are buckling and compression shear failure. The stress–strain relationship curves of the bamboo scrimber and laminated bamboo are also similar. The tensile stress–strain curves showed a linear relationship, and the compressive stress–strain curves can be divided into three stages: elastic, elastoplastic and post-yield. Based on the test results, the stress–strain model was proposed for glulam bamboo, in which a linear equation was used to describe the tensile stress–strain relationship and the Richard–Abbott model was employed to model the compressive stress–strain relationship. A comparison with the experimental results shows that the predicted results are in good agreement with the experimental curves.

胶合层竹子已被初步探索用作结构建筑材料，其轴向载荷下的应力-应变模型在分析竹子成分中具有重要作用。为了研究胶合木竹材的拉伸和压缩行为，在轴向载荷下测试了两种形式的胶合板竹和夹层竹材。研究了它们的力学行为和失效模式。结果表明，竹和层压竹具有相似的破坏模式。对于拉伸破坏，竹纤维断裂，锯齿破坏表面显示为脆性破坏；对于压缩破坏，压缩的两种模式是屈曲和压缩剪切破坏。竹和层压竹的应力-应变关系曲线也相似。拉应力-应变曲线呈线性关系，而压应力-应变曲线可分为三个阶段：弹性，弹塑性和屈服后。根据测试结果，提出了胶合木的应力-应变模型，其中线性方程式描述了拉伸应力-应变关系，而Richard-Abbott模型则用于模拟压应力-应变关系。与实验结果比较表明，预测结果与实验曲线吻合良好。其中使用线性方程式来描述拉伸应力-应变关系，而使用Richard-Abbott模型来建模压缩应力-应变关系。与实验结果比较表明，预测结果与实验曲线吻合良好。其中使用线性方程式来描述拉伸应力-应变关系，而使用Richard-Abbott模型来建模压缩应力-应变关系。与实验结果比较表明，预测结果与实验曲线吻合良好。
