STUDY ON SLIP LOAD BEHAVIOR OF FRICTION TYPE HIGH STRENGTH BOLTED JOINTS HAVING MISALIGNMENT ON THE CONTACT PLANE

Part 3 As to the slip load of the joints fastened by torque control method

Abstract

High strength bolted friction type joints may have misalignment in the contact plane because of permissible deviation of steel plate thickness and so forth. In the first and the second 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, by the fact of the calculated slip load based on the analytical value of the contact force was shown good agreement with the experimental results. This paper shows the slip load applying the proposed analytical method to such joints tightened by torque control method. These slip loads are shown in case of the misalignment on the one side of the main-plates as well as in case of the misalignment on the both sides of the main-plates.
