無機ジンクリッチペイントを塗布した厚板多列高力ボルト摩擦接合継手のすべり耐力の変動に関する2，3の考察

This study focused on the influence of fabrication variations of high strength bolted friction type joint with thick plates. Predominant variations which affect to slip strength of the joint are focused. Slip strength of the joint is evaluated by FEM analysis. The response surface of slip strength of the joint is obtained as considering also interaction terms and second terms of the variations. This paper discusses terms of the variations which affect mainly, based on probabilistic perspective. First terms of the variations contribute almost to slip strength, and the contributions of the other terms are ignorable. A probability which of slip coefficient falls below design slip coefficient is calculated.
