Abstract

Abstract

This study focused on improving the connection stiffness of modern bamboo structures. Total twelve groups, each including six identical glubam specimens with glued-in single threaded rod, were tested to failure in the pull-pull configuration. It was observed that the specimens exhibited four different failure modes, including two types of the shear failure at different interfaces, the yield failure of threaded rod, and the splitting failure of glubam. In order to control yield failure mode, the lower limit of bond length-diameter ratio could be taken as 12.5 and 15 for thread rods of M12 and M16, respectively. Analysis results showed that the bond strength of glued-in single threaded rod in glubam increased as increasing the drill-hole diameter, while it reduced as increasing the bond length-diameter ratio. Typical existing strength models for glued-in rod in timber were not fit to predict the bond strength of glued-in threaded rod in glubam. Based on test data in this investigation, a strength model was also proposed for the glued-in single threaded rod in glubam, and it showed a good prediction accuracy.
