Abstract This paper presents experimental and analytical studies on trusses made of glue-laminated bamboo or glubam, which is a new type of structural material unlike conventional steel or timber. Six full-scale model trusses with two types of configurations and sizes were tested to failure under gradually increased vertical load. The failure of the model trusses was caused by lateral buckling of the top compressive chords. Tests show that the model glubam trusses have adequate stiffness and strength. Analyses were also conducted to model the truss behavior with considering different joint conditions, such as pinned, rigid as well as semi-rigid joint using fictitious members. The analytical results for deformation at the design load level agree with the test results favorably well using all types of joint models. The semi-rigid joint model provides a slightly better prediction to the load carrying capacities of the model trusses. However, the analytical truss model based on pinned joints generally provides conservative prediction to load carrying capacities.
