Abstract
Single-column continuous-curved-beam bridges are often used in earthquake-prone areas, but their design characteristics make it difficult to predict structural damage during an earthquake. A large-scale model of a single-column, continuous-curbed-beam overpass that was damaged during the Wenchuan earthquake was created and tested on a shaking table. After the pier suffered seismic damage it was repaired using a polyurethane cement and re-tested. The results of the study revealed that polyurethane cement repair can improve the structural performance of this type of bridge and is a valid new method for the quick repair of earthquake-damaged bridge piers.
