Bamboo is a green building material that is environmentally friendly and has great development value. However, the limited mechanical properties and heterogeneous dimensions of natural bamboo poles curb the application of bamboo in building structures. A transverse section of engineered bamboo is regular and compact, and its mechanical properties are stable, which can meet the requirements for physical and mechanical properties of materials in modern building structures. Though application of engineered bamboo has just started, it is of great significance to study the connection performance and corresponding influence factors for popularization and application of modern bamboo structures. This paper is focused on a review of research progress for connections in engineered bamboo structures. Firstly, a study on embedding strength and the performance of bolted joints is presented, including calculation methods described with a proposal for future development of standards suitable for the characteristics of engineered bamboo materials. Secondly, research on carpentry joints is introduced, namely tenonmortise joints, nail joints and truss plate joints. Finally, some engineering examples are briefly introduced. This work can provide a reference for further research on connections in engineered bamboo structures.

“…With the improvement of living standards, the demand for environmentally friendly, lightweight, and safe structures has increased dramatically [1][2][3][4][5]. Bamboo as a sustainable alternative to traditional building materials, including wood, has started to gain attention [6][7][8][9][10][11][12][13][14][15] due to its short time to harvest [16,17], the variety of species, as well as the high yield, and the ability to reach a maximum height of 15-30 meters in 2-4 months, and the maximum strength in 3-8 years [18,19]. According to life-cycle assessment (LCA) results, bamboo is included in the "factor 20", which means that its impact on the environment is 20 times less compared to modern alternatives [19,20].…”

Over the past decade, the physical and mechanical performances of laminated bamboo lumber (LBL)-a bamboobased structural material, have been extensively studied using experimental, analytical, and numerical approaches. This paper presents a review of existing knowledge in the literature about the mechanical properties of LBL. The paper involved the review of the response of LBL to different types of loading such as tension, bending, compression, and shear. Based on results of the literature reviewed, the strength of LBL parallel to grain was 90-124 MPa with MOE of 10700 MPa in tension, 29. 55-72.60 MPa, and MOE of 8396-11022 MPa in compression, 63.87-128.4 MPa, and MOE of 8320-10912 MPa in bending, and 7.15-17.5 MPa in shear. The average strength of LBL was similar and in some cases exceeded the average values of bamboo-or wood-based materials, while the variability of its mechanical parameters was lower. The variability in strength values of LBL was affected by bamboo species, density and thickness of bamboo strips, growth portion, type of treatment, strips arrangements, and type of adhesive which in turn calls for classification of LBL by strength grades, degree of hardness, the capability of impregnation and penetration, as well as by areas of application in construction. The study provided and discussed concluding observations, the current research gap, and future research directions on the mechanical properties of LBL.
