作为粘结与高强螺栓摩擦接头混合接缝补强钢板修补方法的基础性研究，本文对采用该方法修补的缺陷钢板进行了单轴拉伸试验。在该方法中，在贴片端的粘接接头和缺陷部位附近的粘接接头之间设置高强度螺栓摩擦接头。拉伸试验的结果表明，胶接接头可以将主板上的应力分散到接线板上。此外，还阐明了粘接和高强螺栓连接的载荷分配比。此外，还提出了各节点荷载分布的简易估算方法。
In this study, as a fundamental study of patch plate repair method by the mixed joint of adhesive and high-strength bolt friction joints, uniaxial tensile tests of de-fective steel plate repaired by the proposed method was carried out. In the proposed method, the high-strength bolt friction joints are provided between adhesive joints in the patch end and one near the defective part. As a result of the tensile tests, it was found that the adhesive joints can distribute the stress on the main plate to patch plates. Additionally, it was clarified that the load distribution ratio of adhe-sive and high-strength bolted joints. In addition, the simple estimation method of the load distribution of each joint was proposed.
