“…Fu et al [73] developed a novel sleeve-cement bamboo joint configuration, utilizing steel sleeves, rings, and mortar for adhesive purposes. They also investigated the performance of sleeve-bolt and groove-plate connections, finding that these joints exhibit brittleness under axial load, with the failure mode being governed by shearing-split.…”

While bamboo’s sustainability and impressive mechanical properties make it suitable for structural use, its application is hindered by challenges in connection systems. Bamboo’s hollow, thin-walled nature, dimensional variations, and anisotropic properties complicate connection design. Despite numerous studies and proposed connection types, a consensus on preferred bamboo connections remains elusive. Ideal connections for raw bamboo structures should be robust, economical, practical, simple, and easy to assemble. This paper reviews 62 scientific papers from the Scopus database published between 2003 and 2024, along with additional relevant references. It identifies research gaps, recommending further studies on bamboo connections considering factors like species, harvest age, treatment type, and node location. The analysis of failure modes and long-term behavior is essential to anticipate and mitigate risks associated with bamboo connections, ensuring durability, and minimizing maintenance needs. Lastly, developing universally accepted standards and codes for bamboo and bamboo connections is crucial for enabling their widespread adoption in the construction industry.

“…The corresponding experiments showed that this connection could effectively improve the load-bearing capacity of connections, and their bearing capacities were related to the strength of the embedded wood. Fu et al [10] put the steel sleeve into the bamboo tube, then injected the mortar between the sleeve and the bamboo inner wall, and finally used steel hoops to reinforce the end of the bamboo tube. Their tensile and compression tests showed that this connection had the good ductility and high load-carrying capacities, and could effectively transfer axial load.…”

The Moso bamboo, a renewable green building material used in various new green buildings, have received extensive attention with the promotion of the concept of green buildings. To explore the mechanical properties of Moso bamboo connections with external clamp steel plates, the 16 specimens were designed by changing the bolt diameters and the end distances of the bolt holes. Their static tension tests were conducted to investigate bearing capacities and failure modes of different connection configurations. Based on test results, three failure modes of these connections were obtained, including the shear failure of bolt shank, bearing failure of bolt hole and punching shear failure of the Moso bamboo. The influence of bolt diameters and end distances of bolt holes on bearing capacities of the connections was quantitatively analyzed. Based on a simplified mechanical model, the analytical models were deduced for the bolt shear failure and the bearing failure of bolt holes. The results showed that the predictive values are in substantial agreement with the experimental results. Finally, the design and manufacturing suggestions are recommended for this Moso bamboo connections.

“…Fu et al [18] proposed a sleeve-cement butt joint, in which the internal wall of the bamboo cavity was roughened, the steel sleeve embedded in the bamboo cavity was perforated and fixed with pin, the cement mortar was injected between the sleeve and the bamboo tube, and the outer surface of the bamboo tube was laterally restrained by a steel ring. The connection strength was provided by the friction force between the mortar and internal wall of the bamboo and the mechanical bite force between the mortar and sleeve.…”

The construction of grouting butt joints of bamboo tubes is simple and efficient. However, when the joint is bent, the low tensile strength of the mortar easily leads to cracking of the mortar prior to the failure of the bamboo tube. In this paper, a comparative test of the bending capacity was performed on grouting butt joints reinforced by nonperforated, fully perforated, and semiperforated steel plates embedded in bamboo tubes to obtain the loaddisplacement curves and ultimate bearing capacity of various specimens. The strengthening effect of CFRP pasted on bamboo tubes was also studied. The results show that the opening at the end of the steel plate is beneficial to resist the slip between the mortar and steel plate, while the complete section in the middle of the steel plate is conducive to making full use of the tensile strength of the steel plate. Therefore, it is best to insert the semiperforated steel plate with openings in the end and without openings in the middle into the mortar to enhance the bending properties of the grouting butt joint, which can make the failure mode of the joint change from brittle failure of mortar to ductile compression failure of bamboo tube. In addition, pasting CFRP sheets on the external wall of the bamboo tube helps to reduce the tensile stress of the mortar, while increasing the width of the steel plate can increase the bending moment of inertia of the mixture of the steel plate and mortar. These two complementary measures are very effective in delaying the cracking of the bamboo tube and improving the bending capacity of the joint.
