| Outline of Final Research Achievements |
In this study, for the purpose of rational design of combined joint, performances of the combined joint consisting of different types of fasteners were verified by experiments, and estimation method for performances of the combined joint were examined. As a result, it was possible to estimate the behavior of combined joint by adding load-slip curves of the individual fastener. And consideration of initial slip of fasteners depending on the clearance of the steel plate hole improved the accuracy of estimation. Further, a method for estimating the yield strength of combined joint was proposed when load-slip curves of the individual fastener was shown in elasto-plastic modeled bi-linear curve.
