Abstract: The creep behavior of bamboo culms under long-term loadings was investigated in the present work.\u00a0Phyllostachys aurea\u00a0bamboo samples were subjected to four-point flexural creep tests at loads corresponding to 30%, 50%, and 80% of the bamboo's short-term bending strength. Creep and recovery behavior were evaluated for each loading level at room temperature over 398\u00a0days, allowing the attainment of primary, secondary, and tertiary creep stages. The failure of one creep test sample occurred at 73\u00a0MPa, and the failure mode due to creep was described. Creep mechanisms assessed included node flexibility, cylindrical bending, and shear. Node flexibility contributed 50\u201374% of total deflection, cylindrical bending contributed 24\u201348%, while shear contributed less than 2%. A four-element Burgers mechanical model was proposed, matching the experimental results for all loading levels. A viscous coefficient parameter of 4.3 to 30\u00d7\u2009103\u00a0GPa.day was inferred, corresponding to the linear dashpot\u00a0n1. These models estimated the bamboo culm deflection over time and predicted failure at a 40% increase in deflection. Overall, this study provided comprehensive insights into the long-term structural behavior of bamboo culms for use in design and engineering applications.<\/strong> The present paper present research results in self-supporting structures employing the tensional integrity structural system applied in the design, architecture, engineering and medicine. Active methods of research and learning developed using experimental models in physical and social environments. Recent advances in research on tensegrity structures have guided the development of prototypes that introduce the biotensegrity system into sustainable architecture and in the design\nof didactic models of the human body. The models developed through studies in biomimetics apply textile-based technologies and flexible connections in biomaterials, environmentally compatible and capable of absorbing forces and special loadings, which are similar to the physiological constitution of\nvertebrate animals and the human body.
