A STUDY ON INFLUENCE OF BOLT AXIAL FORCE ON HIGH STRENGTH BOLTED JOINTS TREATED WITH ZINC-RICH PAINT

Abstract

 It is known that high strength bolted joints treated with zinc-rich paint have a characteristic of large bolt axial force loss by relaxation. In this study, the friction type of high strength bolted connection specimens were made on steel plates, in which contact surfaces have inorganic zinc-rich paint, then slip tests were carried out on these specimens under 15%-additional bolt axial force.
