Until, the most of studies concerning a high strength bolt friction joint was the studies by way of experiment. The distribution of contact pressure and the fricative force is considered that has influences on the stress distribution of contact surface. The purpose of this study is grasping for a difference of dynamics property when changes the thick of splice plate and the coefficient of friction for the circumstances before main slip of the high strength bolt friction type potion by 3 dimensional elastic-plastic model.
