Abstract / Description of output

The mechanical behaviour of the engineered bamboo scrimber connected by self-tapping screws (STSs) is strongly affected by the withdrawal resistance of the STSs in the bamboo scrimber. However, existing knowledge on the withdrawal resistance of STSs in such applications is quite limited. The main objective of this study is to investigate experimentally the withdrawal resistance of STSs inserted in engineered bamboo scrimber and propose an approach to its calculation in structural applications. In the experimental study, pull-out tests were conducted to obtain the load-displacement curves of STS-withdrawal specimens. The key parameters being investigated included the embedment length, the screw diameter, and the screw angle relative to the grain direction. The test results showed that the withdrawal resistance of the STSs connection increased with the increase of the embedment length, the diameter of the self-tapping screw, as well as the increase of the angle between the fiber and the axis of the.
