Abstract
In this paper, two kinds of laminated bamboo lumber specimens with 7 groups of fiber angles on plane A and B were designed. The effects of different angles on the compressive strength and stiffness of laminated bamboo lumber were analyzed. According to the test results, the load displacement curves, ultimate strength values and initial stiffness of all specimens were obtained. The compressive strength test values of pin groove based on American Standard 5% diameter offset method were obtained. The results demonstrated that the compressive strength of the pin groove of laminated bamboo lumber obtained by 5% diameter offset method was relatively uniform. The compressive strength of class A pin groove decreased with the increase of angle. The coefficient of variation was within 9.42%, and the standard deviation within 6.33. The compressive strength of class B pin groove first decreased and then increased with the increase of angle. The coefficient of variation was within 12.10%, and the standard deviation within 6.67. The relationship between different fiber angles and the compressive performance of laminated bamboo lumber were analyzed, and the test results were compared with the theoretical formula calculated in the European wood structure and American wood structure design standards. The calculation model of pin groove compressive strength with different fiber angles was put forward.
