Abstract
For developing the high-strength bolted friction joints with the higher slip resistance than the conventional ones, a new friction joint using the plate washers and the main plate with zero hole clearance is proposed here. The external applied load is transmitted by the frictional forces acting on the contact area of the main plate, the lap plates and the plate washers fastened by the bolts. Especially, the frictional resistance between the plate washers and the lap plates is dependent on the bearing resistance of the plate and the shear resistance of the bolt. The static tests of the proposal friction joints with single bolt and the conventional ones are conducted. The slip load, the basic joint behavior and the fracture mode are discussed. And then the relationship between the slip resistance and the thickness of the main plate is investigated.
