Abstract
ABSTRACT To determine the shear behavior and slip resistance of metal plate joints of laminated bamboo lumber (LBL), considering the influence of sizes (length and width) and angles of metal plates, 100 specimens were tested. When the angle of the metal plate is different, the force modes can be divided into three types: pure shear, shear-tension, and shear-compression modes. According to the test results, the shear-tension modes of metal plate joints have the strongest bearing capacity, followed by the pure shear mode in second place and the shear-compression mode in last. The change in the size of the joints dramatically influences the ultimate load. Based on the test, the load-slip curves of the shear metal plate connected joints of LBL were fitted by the Foschi formula, and the fitting results were in good agreement with the test results. Finally, the ultimate shear strength of LBL joints was compared with that of other wood/bamboo composites. The results show that the shear performance of metal plate joints of LBL is better than that of ordinary wood materials. The test provided a reference for the engineering structures and finite element numerical simulation analysis of metal plate connected joints of LBL.
