Abstract
A method of improving earthquake resistance of existing spillway piers provided in a dam. The method includes a following step. End portions of a main beam and top portions of existing spillway piers are connected to each other with a high damping device having a history damping property with high primary rigidity. The high damping device has a yield displacement amount in seismic velocity smaller than a tolerance of a displacement amount of the existing spillway piers. The high damping device has a yield load value in seismic velocity greater than a maximum seismic force generated therein in a bridge-axis direction due to a large-scale earthquake.
