; Until , the most of studies concerning a high strength bolt frictioll joint was the studies by way of experiment , The distribution of contact pressure and the fr重 cative force is considered that has inf 玉 uences on the stress distribution of 亡 ontact surface . The purpose of this study is grasping for a difference of dynamlcs property when changes the thick of splice plate and the coefficient of frict 呈 on for the circumstances before main shp of the hlgh strength bolt friction type potion by 3 d正 mensional elastic − plast孟 c model .
