Resilient Bridges

Typical reinforced concrete bridge columns in California are designed to be ductile. After an earthquake, they may have large residual displacements and permanent damage, which may require repair. This research project focuses on introducing structural fuses in the column bent to eliminate or minimize column damage during earthquakes. Hysteretic behavior of the structural fuses can help protect bridge columns by dissipating the energy absorbed by the structure. Representative Caltrans bridges are developed to investigate how to implement the structural fuse concept in typical California bridges and achieve the desired system behavior.
