ABSTRACT
The article focuses on efforts to make earthquake resistant bridges. Researchers have found that structures can survive earthquakes if their columns are ductile. Earthquake engineers are trying to provide more resilience through better detailing, capacity-protected members, isolation and increased damping. Bridge columns in California are regularly wrapped in steel or fiber jackets that allow but confine movement. Expansion joints have cable restrainers. Shear force transfer designs allow for both horizontal and vertical movement.
