To improve the utilization rate of bamboo, glued laminated bamboo hollow column (GLBHC) was examined under eccentric compression to study the effects of different slenderness ratios, eccentric distances, and wall thicknesses on its ultimate bearing capacity. The nonlinear deformation of the material and the P-delta effect of the column occur under eccentric compression, which can affect its ultimate bearing capacity, so it is very important to analyze the elastic-plastic buckling of the column. Moreover, the discontinuity of the hollow column section aggravates the nonlinear deformation. To accurately estimate the ultimate bearing capacity of GLBHC, considering the difference in tensile and compression elastic modulus, two eccentric compression models were established. A formula for ultimate bearing capacity of the GLBHC under eccentric compression was proposed, and the calculated results were in good agreement with the test results.

Bamboo has been studied and utilized quite significantly in recent years because of its advantages such as short growth period, good appearance, environmental protection and superior mechanical properties. Bamboo is processed into profiles to address inherent issues with size limitation and self-defects and use of BFRP can enhance the mechanical properties of bamboo for widespread application. In this paper, the mechanical properties of BFRP strengthened chamfered laminated bamboo lumber (LBL) columns with four eccentricity e0 of 30 mm, 60 mm, 90 mm, and 120 mm were tested. The strengthening effect of BFRP on the performance of LBL columns subjected to eccentric loading was compared with the specimens without any reinforcement. Several analytical models to capture the mechanical performance of BFRP reinforced LBL columns with different eccentricities have been proposed in the current study.

“…Just 3-5 years from the time of planting is needed for bamboo [9][10][11][12][13][14][15]. Besides the above advantages, bamboo also has high efficiency in comparison to other construction materials, and its strength-to-weight ratio is greater than that of common wood, aluminum alloy, cast iron, and steel [15][16][17][18][19][20][21][22].…”

With so many advantages such as environmental friendliness, fast-growing, high strength-to-weight ratio, sustainability, and the capability of being reused or recycled, bamboo structures has gained more and more attention for scientists. This paper shows the feasibility of the design of an office building using laminated bamboo lumbers in compliance with the Chinese standards as GB50009-2012, GB50011-2010, GB50016-2014, and GB 50005-2017. Detailed information about the materials and building were offered. A lot of related construction photos were offer to show the building process. This case is a very good application example for laminated bamboo lumber buildings and has attracted many engineers’ attention in industrial field. Laminated bamboo lumber structures should have a bright future. It should become one main structure form in civil engineering area. However, due to none existing engineered bamboo structures design standard now, engineers have to take reference to standards for timber structures. Setting up the standard system is very important for engineered bamboo structures’ application. Through more and more scientists’ hard working, it might be not a long way to build the code system.
