To investigate the compression performance of laminated bamboo, 210 laminated bamboo specimens were tested using seven different lamination angles. Six failure types were classified. All the specimens experienced elastic stage at the beginning of the loading process and then elastic-plastic stage. At the end of the elastic-plastic stage, specimens of ${\text{15}}^{°}$, ${\text{30}}^{°}$ and ${\text{45}}^{°}$ immediately reached the ultimate bearing capacity, showing brittle failure, while other specimens entered a longer plastic stage before failure. The off-axis compression strength and the apparent elastic modulus both decreased with the increment of the angle. Two empirical formulas were proposed to predict the off-axis compression strength and apparent elastic modulus of laminated bamboo compared with several well-known failure criteria. The Poisson’s ratio in A/C planes increased with the increment of the angle while in B/D planes, it increased and peaked at ${\text{30}}^{°}$ before decreasing. Based on Ramberg-Osgood relation, the compression and shear stress-strain curves were fitted.

为了研究层压竹的压缩性能，使用七个不同的层压角度测试了210个层压竹样品。分为六种故障类型。在加载过程开始时，所有样本都经历了弹性阶段，然后是弹塑性阶段。在弹塑性阶段结束时，${\text{15}}^{°}$， ${\text{30}}^{°}$ 和 ${\text{45}}^{°}$立即达到极限承载力，显示出脆性破坏，而其他试样则在破坏前进入了更长的塑性阶段。离轴压缩强度和表观弹性模量都随着角度的增加而减小。提出了两个经验公式来预测层压竹的离轴抗压强度和表观弹性模量，并与几种众所周知的破坏准则进行了比较。A / C平面中的泊松比随角度的增加而增加，而在B / D平面中的泊松比则随角的增加而达到峰值。${\text{30}}^{°}$在减少之前。基于Ramberg-Osgood关系，拟合了压缩和剪切应力-应变曲线。
