Advanced method for lightweight steel joining

Abstract In this paper, a new joint-type for steel sheet jointing is presented. The joint is called the Rosette joint and it is formed using the parent metal of the sections to be joined. The Rosette joint contains two different parts: the collar and hole. The collar is pressed by a special tool around the perimeter of the hole part which forms the final connection. The joint is specially developed for fully integrated and highly automated steel frame panel or steel truss production lines. In experimental research, a series of shear tests on the Rosette joint were carried out. On the basis of the tests and analyses, some further improvements were carried through to the connection details. The results of this research project show that the new Rosette joint is suitable and effective for the above-mentioned applications.
