Experimental and numerical study on timber-to-bamboo scrimber connection with self-tapping screws

Abstract

The main objective of this study is to investigate the shear performance of timber-to-bamboo scrimber connection with self-tapping screws. Firstly, single-shear tests were conducted to obtain the load-displacement curves of timber-to-bamboo scrimber connections in the experimental study. The key parameters being investigated included the diameter, number and angle relative to the grain direction of the screw. The test results revealed that the shear capacity of the connection increased with the increase of the screw diameter and number, as opposed to the rise of the angle. Then, the finite element model for specimens has been verified by comparing it with the experimental data and used to conduct a numerical analysis of the connection.
