典型胶合竹剪切强度试验研究
|
摘要
针对4∶1典型纤维配比的格鲁斑胶合竹材进行面内剪切与面外剪切试验,通过研究相关的规范和结合材料本身的特性以及参考《木材物理力学试验方法》、ASTM D 143-94《木材无疵小试件的试验方法》等制定了剪切试验的夹具与试验方法,并得到面内剪切与面外剪切的强度平均值,同时利用统计学相关知识对剪切试验数据进行分析,发现:Weibull分布能较好地描述面外剪切的分布规律,正态分布能较好地满足面内剪切的分布特点。试验结果表明:加载方式与纤维的排列对格鲁斑胶合竹材的剪切强度影响较大。通过与其他几种常见建筑材料比较,表明格鲁斑胶合竹材能够满足剪切强度的要求。
Based on current specifications timber materials,such as Wood Physical and Mechanical Properties Test Methods and Standard Test Methods for Small Clear Specimens of Timber(ASTM D 143-94),it was conducted shear tests of glue laminated bamboo(Glu Bam),with different loading configurations related to the main fiber orientation.It was obtained the average value of in-plane and out-of-plane shear strengths and found out by statistical analysis of the shear test data that:Weibull distribution could be used to describe the distribution of the out-of-plane shear strength,normal distribution could better meet in-plane shear strength.The results showed that fiber arrangement and loading have great influence on shear strength.By comparing with several other common building materials,Glu Bam could meet the shear strength requirements of structure.
