Seismic retrofitting of bridges using slide bearings with bending-type anchor bars

ABSTRACT: The bending-type anchor bar as schematically shown in Figure 1 is expected to have a large energy dissipation ability based on the plastic deformation of mild steel, thus providing an effective device for retrofitting bridges to protect them from seismic attack. In this report, theoretical and experimental studies are presented for implementing seismic retrofitting of bridges.
