Abstract

Bamboo is a renewable and environmentally friendly material often used for construction. This study investigates the flexural behavior of bamboo beams through theoretical and finite element (FE) analyses. Considering the material’s nonlinearity, a method of calculating load-deflection curves is proposed and validated via FE analysis. The interfacial slippage dominated by the shear stiffness of the interface between two bamboo poles significantly influences the flexural behavior of double-pole bamboo beams. Thus, the load-deflection curves for different shear stiffnesses can be obtained via theoretical and FE analyses. Subsequently, a novel configuration using diagonal steel bands to avoid slippage is presented. An inclination angle of 45° is suggested to adequately develop the stiffness and bearing capacity of the steel band.
