The creep behavior of bamboo due to the complicated influences of environment and stress will lead to a sustained increase in deformation, which serious effects the service performance of structures. To investigate the creep behavior of recombinant bamboo, twenty-four recombinant bamboo specimens were tested under lasting compressive and tensile loads at different load levels. The typical failure modes of recombinant bamboo under a lasting load at a high load level were buckling failure and brittle fracturing due to creep compressive creep and tensile creep development, respectively. At a high load level, the creep deformation of recombinant bamboo initially develops unsteadily and increases rapidly until failure; at a low load level, creep deformation rapidly develops in the early stage and stabilizes in the middle and late stages. The load level has notable effects on the overall creep deformation and the proportion of creep deformation. The residual deformation of creep will generally increase and the recovery of creep will decrease with increasing load level. Based on the Burgers model, predictive models that can take the load levels into account were proposed to evaluate the compressive and tensile creep behaviors of recombinant bamboo. The proposed models can be used to accurately evaluate the strain-time behavior of recombinant bamboo.
