摘　　要：利用竹胶合板与L型钢制备用于竹结构房屋支撑作用的竹质建筑结构柱,采用双向刀铰与500吨长柱试验机对其进行静态抗压测试,测量结构柱抗压性能,观察其在轴向压力作用下的压缩、弯曲变形,分析竹帘胶合板力学性能、连接方式、破坏形式等对结构柱力学性能的影响。结果表明:竹质建筑结构柱结构柱破坏荷载为700 kN,抗压强度为33.26 MPa;竹质建筑结构柱端部出现局部受压破坏;竹质建筑结构柱翼缘与侧板之间的螺钉连接强度不高,两者之间所受剪力不能有效传递。The bamboo building structural column was made up of bamboo plywood and L-shaped steel for supporting bamboo structural house, and was pressured by using the bi-directional knife hinges and the 500 tons static load and long column test machine. The pressure resistance of the column was measured and the compression and bending deformations under axial pressure were observed, and the effects of mechanical property, connection methods and damage form of bamboo curtain plywood on the mechanical performance of bamboo building structural column were analyzed. The experimental results indicate that the damaged load of the bamboo building structural colurma was 700 kN and its compressive strength was 33.26 MPa; the local compression failure occurred in the end of the bamboo building structural column; the screw fastening strength between the flanges and the lateral plates of the column were not high, and the shearing force between the the flanges and the lateral plate could not be passed effectively.
