Abstract

Applications of the diagrid structural system have recently increased, and substantial analytical studies have been conducted. However, the structural behavior under lateral loadings, such as wind and earthquake loads, cannot be fully understood through only analytical approaches, due to the complexity of diagrid nodes, and challenges of modeling the welding properties. Therefore, in this study, four web-continuous diagrid node specimens were tested under cyclic loads. Welding methods and design details were selected as testing parameters. The effects of the welding methods and design details on the initial stiffness and yielding stress were found to be not significant. However, the failure mode and energy dissipation of the nodes were significantly affected by the welding methods, and the design details.
