摘　　要：重组竹是一种将竹材重新组织并加以强化成型的竹质复合材料,介绍了4根由重组竹制作的方形截面柱的轴心受压试验研究,通过数据分析及理论计算,初步探明了方形截面重组竹柱在受压时的承载能力及破坏形态,结果表明其破坏是杆件丧失整体稳定性所致,并没有出现强度破坏;试验所得的压杆稳定承载力与理论计算的临界荷载接近,为重组竹柱应用于建筑结构提供了可靠的参考价值。Recombinant bamboo column is a kind of bamboo compound material which is reorganized and then strengthened as a form. The axial compression experiments by 4 square section columns which were made from recombinant bamboo columns were carried out. Through data analysis and theoretical calculation, the bearing capacity and failure mode of the columns under compression were preliminarily put forward. The results show that the damage was caused by the loss of the whole stability of the bars, it wasn＇t the strength. The stability pressure load resulted from experiment gave a good agreement to the critical load obtained from the theoretical calculation, which provided a reliable reference for recombinant bamboo columns to use in building structure.
