摘要:
为了获得圆竹的主要力学性能及其影响因素，完成了6组共计51个试件的试验研究，获得了圆竹的抗压强度、环刚度以及抗弯强度等力学性能，研究了含水率、竹节和取材单元对上述力学性能的影响.结果表明：竹材顺纹抗压强度分别为弦向横纹和径向横纹抗压强度的2.7倍和4.0倍；竹节的紧箍作用有效提高了圆竹的环刚度，节部材较节间材提高90%；竹节对竹材的抗压强度具有一定的提高作用，节部材较节间材提高6.3%；含水率对圆竹抗压强度和抗弯强度有较大影响，但其影响趋势不同.圆竹的抗压强度随竹材含水率降低而增加，含水率降低40%时抗压强度提高约20%，而其抗弯强度随竹材含水率的降低而降低，在挠度相同的前提下，抗弯强度下降约20%
Abstract:
In order to obtain the main mechanical properties and influencing factors of the bamboo culms, this paper complete tests of 6 groups a total of 51 specimens, which result in the longitudinal compressive strength, radial compressive strength and chord compressive strength of bamboo sheets, radial compressive strength and bending moment of bamboo culms. And carry out the influencing research of moisture content and bamboo nodes. The results show that the longitudinal compressive strength of bamboo sheets is almost the 2.7 times of radial compressive strength of bamboo sheets, and almost the 4.0 times of chord compressive strength of bamboo sheets. The radial compressive strength of bamboo culms with nodes increases 90% than the without nodes. The longitudinal compressive strength of bamboo culms with nodes increases 6.3% than the without nodes. The longitudinal compressive strength of bamboo culms increases with the decrease of moisture content, which shows that moisture content decreases by 40% while the compressive strength increased by about 20%. The bending moment of bamboo culms decreases with the decrease of moisture content, which shows that moisture content decreases by 40% while the compressive strength decreased by about 20%
