High strength bolted friction type joints may have gap in the contact plane because of permissible deviation of steel plate thickness. In the “Part 1” of last paper, we proposed analytical method to evaluate the slip load of such joints tightened by turn-of-nut method. The validity of the proposed analytical method was verified, because the calculated slip load by the analytical value of the contact force was in good agreement with the experimental results. We consider popular three methods which may prevent from the reduction in slip load of gapped joint. One is the way increase the preliminary tightening torque value, the other is increase the nut rotation of tightening, further, the effect of the bolt location are discussed based on the analytical method which is described in the last paper.
