在这项研究中，钉接头假定用于剪力墙的木屋暴露在高温和高湿度，以加速生锈的发展，对钉。对劣化后的试件进行了剪切试验。结果表明，1.随着锈蚀的发展，失效模式有从拔出到钉头拉穿的趋势。在破坏初期，钉的强度等级足以代表抗剪性能的变化趋势，而在破坏后期，其他参数更能反映抗剪性能的变化趋势.此外，还尝试将桩侧阻力公式应用于荷载-变形关系的简化预测，并通过简单单元试验估算出桩侧阻力的特征值。
In this study, nailed joints supposing to be used in the shear walls of wooden houses were exposed in high temperature and humidity in order to accelerate rust development on the nails. The shear tests were conducted on the deteriorated specimens. As the result,1. As the rust development progressed, the failure mode tended to change from withdrawal to nail-head pull-through.2. The rating of the nail was adequate to representing the tendency of the shearing performance at the early stage of deterioration, but the later stage, the other parameters were more appropriate.3. The each factor of the allowable resistance showed different tendencies, as the deterioration advanced.In addition, the formula of the lateral resistance for the piles was tried to apply to the simplified prediction of the load-deformation relations with characteristic value estimated by simple element tests.
