Abstract

Considering the influencing factors length and bending direction, 124 small size specimens and 12 beam specimens of laminated Moso bamboo were manufactured and tested under static loading. Detailed discussions on how the length influences the bending performance of laminated Moso bamboo are presented in this paper. The bending directions have an influence on the strength but not very significant as a whole. No matter how long and which bending direction, each specimen showed a similar tensile failure process with increasing loading. Comparison of the two orientations of the small specimens indicates that the strength and modulus of elasticity values for tangential bending direction had increased over the values for radial bending direction. The length has an influence on the static bending properties of laminated Moso bamboo but not very clear. In addition, the formulas for calculating the ultimate bending moment and ultimate bending deflection were discussed under nonlinear conditions.
