Based on analysis of the bearing capacity of the bolted connections for bamboo scrimber,the applicability of the wood structure design codes in calculating the bearing capacity of the bolted connections for bamboo scrimber was evaluated. A total of 48 specimens in 16 groups designed by orthogonal scheme were tested in this study. Firstly, the applicability of Foshci's theory model was verified. Then, the effects of bolt diameter, end distance and main component thickness on the bearing properties of bolt connections were analyzed. Finally, the accuracy of design codes GB 50005 and European 5 in calculating the bearing capacity of the bolted steel-BS-steel connections was evaluated. The result showed that Foschi's theory model could reflects the change characteristics of both the linear elasticity and post-yield phases, which also expressed depicted the whole bearing processes of the connections, comprehensively. The bearing capacity is affected by bolt diameter, main component thickness and end distance, and it is affected by the bolt diameter most obviously when the connection meets the minimum requirements of size design. Besides, Eurocode 5 is so conservative in calculating the bearing capacity of the bolted steel-BS-steel connections. There is a safety reserve in calculating the bearing capacity by GB 50005, which is more suitable for calculating the bearing capacity of the bolted steel-BS-steel connections than Eurocode 5.
