| 要旨 |
This study investigates the seismic behavior of bridge with strengthened pier, and also the behavior of bridge when foundation strengthening was imposed. Seismic responses of bridge were compared by conducting pseudo-dynamic test, in which, foundation was selected as an experimental part. Two cases of foundation specimens have been constructed in order to represent a normal foundation and a strengthened foundation. Damage in the piles was observed in the normal foundation with pier strengthening case, whereas the pier was damaged in the strengthened foundation case. |
