摘要: AbstractUsing seismic isolation systems for highway bridges modifies the structure’s principal vibration modes and effectively reduces base shear conveyed from superstructure to substructure. However, some low-damping rubber bearings, large displacements can be a problem. Supplemental hysteretic dampers introduced into base-isolated bridge, which might nevertheless increase structure shear, merit of adding has evaluated properly. In this paper, simplified method was implemented design low-cost damper, resulting isolator-damper system tested experimentally. The used is based on an equivalent linearization approach. A full-scale elastomeric bearing characterized in damper. Both isolator damper went through cyclic testing real-time dynamic substructuring (RTDS) methods verify capacity ba...
