箍筋增强型胶合竹柱抗压试验

Compressive strength test on bamboo column reinforced by clamps

竹片经过胶合形成的竹柱构件,克服了竹材形状各异的缺点,使之能够运用到各种建筑和桥梁结构之中,但由于竹片之间黏合的原因,竹柱构件受压破坏时常出现竹片层间劈裂。为改善胶合竹柱的受力性能,笔者提出箍筋增强型胶合竹柱设想,并对其进行了静力试验;结果证明箍筋改善了竹柱的工作性能,提高了竹柱的极限承载能力。

Bamboo column prepared by gluing bamboo strips can avoid problems caused by the shape diversity of bamboo and is suitable for structural applications in buildings and bridges. However, delamination often occurs when bamboo column is subjected to compression. In this study, bamboo column reinforced by clamps were suggested to improve its mechanical performances. The test results showed that clamps improved the loading capacity of the column.
