Abstract

The Diagrid structural system is considered to be the best structural system for constructing free form structures, but it is also a very effective system for resisting lateral load. As a newly investigated structural system, its complicated node has not yet been completely investigated, and only minimal experimentation with the manufacturing and construction of the system has been conducted. Therefore, the construction cost of the diagrid structural system is still comparatively high. In this study, the cyclic performance of a diagrid node with an H-section brace is discussed with an emphasis on the welding methods, overlapped length, and diagrid angle. Details considering productivity were proposed, and their structural performance was assessed through experimental and analytical investigation.
