STATICAL CHARACTERISTICS OF FILLET WELDED JOINTS USING VERTICAL CONNECTING PLATES

Abstract

In this paper the outline and test results of the experimental study about fillet welded joints using vertical connecting plates. 5 kinds of specimens concerning of this type joint were designed (see Fig.2, Fig.3) to investigate the statical characteristics of the joints. The parameters are width and thickness of vertical connecting plates, length and size of fillet weld and existence of boxing welds. It becomes clear that the maximum strength and plastic deformation ability of fillet welded joints using vertical connecting plates is little smaller than that of usual fillet welded lap joints using splice plates in case fracture mode 4 (see Fig.5) occurred. The height to thickness ratio of the connecting plate has a major influence on the maximum strength of this type of the fillet welded joints.
