Nonlinear response characteristics of bridges with hysteretic dampers between the abutment and the deck subjected to severe ground motions

Abstract

Dampers are useful for bridges to reduce structural response by their energy absorption. It is important that excessive seismic response is not developed even if bridges are subjected to severe ground motions. Seismic response characteristics of bridges with hysteretic dampers between the abutment and the deck subjected to severe ground motions were investigated. It was shown that the summation of the yield seismic coefficients of the bridge columns and dampers is an important parameter to reduce excessive seismic response under severe ground motions.
