Shear Behavior of the Lamined Bamboo Guadua (LBG)
C. Takeuchi, D. Linero
Abstract. The shear behavior parallel and perpendicular to the fiber of laminated bamboo Guadua, LBG, was studied by testing six different types of samples. The definition of the types was made taking into account the direction of the fibers, the orientation of the slats and the shear plane. In all configurations, the shear between the parenchyma matrix and fibers was studied.
The samples whose fibers and boards were parallel to the direction of the load presented a crack parallel to the fiber whose surface mostly coincides with the expected cutting plane. The average value of shear strength of LBG was 6.0MPa, when the fibers are parallel to the loading direction and the contact surface between slats is perpendicular to the shear plane. In the samples where the fibers are perpendicular to the loading direction and to the contact surface between slats, the crack propagated approximately 45° from the vertical and the shear strength was 2.9MPa. In the samples in which the direction of the load was perpendicular to the fiber and parallel to the slats, the crack was parallel to the expected shear plane. In some of these samples, the crack path did not coincide with the expected shear plane, occurring in other parallel planes with lower fiber density. This case presented the smallest shear strength with average value of 2.3MPa.
