Bamboo is a composite material reinforced by fibers called bundle sheaths. It also has functionally graded structures on macro-and micro-scales. Bamboo has a cylindrical structure with many nodes, and its diameter and thickness vary with height from the ground, which is called the macroscopic graded structure. The fibers are densely distributed in the outer region, which is called the microscopic graded structure. This report presents an analysis of the large-deflective behavior of bamboo based on large-deflection beam theory. The analysis takes gravity and wind load into consideration The beam is modeled using the measured data of the sample bamboo. The maximum surface stress of the bamboo culm keeps approximately a constant even if wind load increases. Unique and smart structural behavior of bamboo deflection is described with respect to the graded structures.
