摘要

以4年生毛竹为对象,分别按照国家标准、行业标准和国际标准的方法,进行顺纹抗剪强度的测试。结果表明:测试方法、试件形状以及加载速度对抗剪强度均有显著影响;行业标准的试件形状能较准确测出竹材的纯抗剪强度,综合测试时间,加载速度以0.8～1.5mm/min为宜。

Abstract

In this study,three test methods from different standards,including Chinese National Standard GB/T,Construction Industry Standard JG/T,and ISO Standard,were used to evaluate shear strength parallel to grain of 4-year Moso bamboo(Phyllostachys pubescens) samples.Shear strength related to specimen shape and loading speed was also evaluated.The results showed that: 1) there were significant differences among three test methods and specimen shapes;2) loading speed had considerable influence on shear strengths.It was found that the test configuration specified in the Construction Industry Standard was more suitable for testing shear strength,and the loading speed was suggested from 0.8 to 1.5 mm/min.
