ABSTRACT
ABSTRACT: Main objective of this study is to prevent brittle failure and to enhance the strength of fastener joint such as the bolt or drift-pin joints through local reinforcement or GIR (glued-in rod) system. The tension tests were carried out to confirm the effect of the strengthening method for fastener joints using bamboo plywood or bamboo GIR system. From test results, the local reinforcement members and the effect of the member size on the mechanical behavior of the joint were discussed. The performance of the strengthened joint was improved. From test results by the GIR system, the effect of the distance between the bolt and the GIR on the mechanical behavior of the joint was discussed. In addition, 3-D non-linear finite element models were developed to simulate structural behavior of the fasteners strengthened by typical local reinforcement and GIR system. Reasonably good correlation was obtained.
