SEISMIC: Resilient Bridges: Replaceable Structural Fuses for Post-Earthquake Accelerated Bridge Construction/Repair under Continued Service - Phase I: Analytical Investigation

In a post-earthquake perspective, Accelerated Bridge Construction (ABC) implies an ability to expedite bridge repairs, and if possible, execute those repairs while keeping the bridge open, or at worse limiting disturbance by requiring only short duration closures (typically, accomplishing work at night). Structural Fuses are attractive because they can be effective in dissipating hysteretic energy in select structural element separate from the columns, in a way such that the columns are left intact and the Fuses can be removed and replaced. This requires special design considerations, as well as research to create Structural Fuses systems that would be appropriate for selected applications.
