Four groups of twenty bolted connections with metal plates for laminated bamboo board were tested by compressive load. A 3 D nonlinear finite element(FE) model of bolted connections was developed incorporating ABAQUS FE software. The effect of board thickness and bolt diameter on stiffness, yield strength and failure mode were analyzed. It is shown the nonlinear finite element analysis can be used to predict the stiffness, yield strength and failure models of the bolted connections, for the results obtained by FE analysis agree well with those obtained by the test. Both the stiffness and the yield strength increase linearly with increase of bolt diameter. The ultimate strength and ductility of bolted connection are improved by increasing the thickness of bamboo laminated board. Besides, the failure models of bolted connection are affected by bolt diameter and the thickness of bamboo laminated board. When the failure model is typeⅠ, the strength of bolt and bamboo laminated board can be fully performed, and the ductility and mechanical properties of bolted connection are all in good state.
