DuraFuse Frames ARW
Retrofitting pre-Northridge steel moment connections presents significant
challenges. DuraFuse Frames ARW adds ductility and stiffness to existing connections without altering beam-column welds. Its vertical fuse plates are replaceable and can be sized to minimize or eliminate the need for strengthening other components, such as the beam, column, and panel zone. The increased connection depth enhances frame stiffness and reduces demand on non-ductile welds. Full-scale testing with pre-Northridge weld practices and materials has demonstrated the retrofit’s strength and ductility. DuraFuse Frames ARW offers a direct, efficient solution for achieving economy, safety, and repairability.
