Abstract

Steel portal frames in the construction industry typically comprise 1 and H sections. The design procedures for the connections in these frames (base, eaves and apex) are well established. This research is based on using rectangular hollow sections as the column and rafter members.

The eaves connection of a rectangular hollow section pitched portal frame is investigated in this report and includes a literature review of various experimental research relating to moment connections between rectangular hollow sections.

Three eaves joints were considered in this research. The joints were physically tested in the laboratory and a finite element analysis carried out. An initial design approach for predicting the moment-rotation relationship for the joints was formulated. Good correlation between the laboratory, finite element analysis and initial design approach was found, in particular for the linear elastic behaviour of the connection.
