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.
