Abstract
To investigate the anisotropic behavior of parallel bamboo strand lumbers (PBSLs), flexural properties of seven kinds of PBSL beams with different fiber orientations were tested. It is found that the bending strength and stiffness decreases with the increase of the angle between the fibers and the beam axis. When the fibers are not parallel to the beam axis, the PBSL beam has an interfacial failure judged from the crack evolution. To reveal the coupling effect between the shear deformation and the axial tension/compression deformation induced by the anisotropy, first-order anisotropic beam model is proposed. Based on the tensile-shear failure of fibers or matrix, composite failure criteria for PBSLs were proposed to predict the ultimate load. The research also suggests a method to get material properties of PBSLs based on flexural experiments and failure analyses.
