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.
