The Strength of 100 percent Overlapped Multiplanar KK-Joints of Square Hollow Sections

摘要

The strength of multiplanar overlap KK-joints in square hollow sections (RHS) and their counterpart uniplanar overlap K-joints are studied in more detail in order to determine the multiplanar effect. In this study the RHS sections are square. This paper deals with 100 percent overlapped multiplanar overlap KK-joints in RHS. In this FE study a basic KK-overlap joint with beta = 0.4 and 2 gamma = 15, 25 and 35, has been considered. Based on this study the relationship between the strength of multiplanar overlap KK-joints and uniplanar overlap K-joints has been determined. Further comparisons are made with existing design recommendations.
