“…Fu et al [67] 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. 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 widespread adoption in the construction industry.

“…However, the weight of joints as well as the structures has increased by at least 2.5 times [56], and in the case of long-term use, due to the different shrinkage-swelling rates of cement mortar and bamboo, cracks gradually occurs between the materials so that the materials are separated from each other and cannot continue to work together. Fu et al [57] designed a kind of joint, in which the prefabricated steel sleeve was first inserted into the cavity of raw bamboo, then the cement mortar was injected between the sleeve and the bamboo wall, and finally the joint was restrained by steel rings (Fig. 26).…”

Bamboo is a green construction material in line with sustainable development strategies. The use of raw bamboo in architecture has existed since ancient times. In the long development years of original bamboo buildings, many areas in the world gradually formed unique bamboo buildings, which have become an important local cultural feature. For building structures, joints are the key to ensure structural load transfer. Because of hollow and thin-walled material property of bamboo, the connection in raw bamboo buildings has always been a major difficulty and problem in the application of bamboo, which seriously hinders the development of original bamboo structures. In order to promote the use of raw bamboo, two traditional connection methods in raw bamboo structures are described in this paper firstly, with the advantages and disadvantages of the two methods pointed out. Also, research progress on four categories of raw bamboo building joints is described namely, bolt joints, steel member joints, filler reinforced joints and other types of joints. This work can provide a reference for future research and engineering applications.

“…However, their tests only used bamboo pieces instead of complete bamboo tubes, therefore it is not entirely applicable to practical engineering. Fu et al [19] proposed a configuration of sleeve-cement bamboo joint and carried out the tensile and compressive test on it. The tests showed that this connection has a good ductility under tension and high strength under compression, and can transfer axial loads in the bamboo joint effectively.…”

Moso bamboos have attracted excessive attention as a renewable green building material to the concept of sustainable development. In this paper, the 20 bolted Moso bamboo connection specimens with embedded steel plates and grouting materials were designed according to connection configurations with different bolt diameters and end distance of bolt holes, and their bearing capacities and failure modes were analyzed by static tension tests. According to the test results of all connectors, the failure modes of the specimens are divided into four categories, and the effects of bolt diameter and bolt hole end distance on the connection bearing capacity and failure mode are analyzed. The test results show that the deformation and failure process can be divided into four stages. The main influence factor of connector bearing capacity is bolt diameter. Connectors can be divided into four failure modes, and brittle failure can be avoided by adopting certain structural measures. Filling with grouting material can improve the bearing capacity of joints. Due to the large variability of bamboo, further experiments are needed.
