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.

研究了采用形状记忆合金（SMA阻尼器）和带预应力钢束的屈曲约束支撑（BRB）或屈曲约束波纹板阻尼器（RPD）组成的自定心阻尼器对钢桥结构抗震性能的改善效果。对裸框架和安装了自行设计的阻尼器的框架进行了动力分析，结果表明，该阻尼器具有良好的复位能力和耗能能力。
