Abstract:

Bridges designed with current seismic codes exhibit large displacement capacities, and the bridge total collapse is prevented. However, damage of ductile members is allowed at this performance level. In reinforced concrete bridges excited by ground shaking, columns are the target ductile members in which concrete cover, core, and reinforcement may damage, and the column may not return to its original position. Minor damages are usually repaired but excessive damages such as core crushing, bar buckling, and/or bar fracture are hard to repair and will usually result in the column or bridge replacement. According to FHWA, approximately 25% of the US bridges require rehabilitation, repair, or total replacement.
