| Research Abstract |
The effectiveness of seismic performance upgrading for steel bridge structures is studied by adoption of self-centering damping devices made of (1) shape memory alloys (SMA damper) and of (2) buckling-restrained brace (BRB) or buckling-restrained rippled plate dampers with steel prestressing tendons. Dynamic analyses of bare frames and frames with developed self-centering dampers show that excellent re-centering ability and energy dissipation can be afforded.
