摘　　要：金属阻尼器凭借金属材料屈服之后的耗能能力成为结构抗震领域的重要手段,但在桥梁工程中的应用还相对较少。将桥梁工程中使用的金属阻尼器分为传统的墩梁间金属阻尼器和框架式桥墩间的屈曲约束支撑2大类,介绍了不同形式的软钢阻尼器、减隔震支座、形状记忆合金阻尼器、主要应用于框架式桥墩柱间的金属屈曲约束支撑及带有自复位功能的耗能支撑等金属阻尼器在国内外的最新研究进展。Due to energy dissipation capacity of metallic materials after yielding,metal dampers become an important means in the field of structural seismic mitigation,but their application in bridge engineering needs to be improved.In the article,metal dampers utilized in bridge engineering are divided into two types:traditional metal beam dampers between piers and beams and buckling restrained braces between frame bridge piers and latest applied research developments in China and other countries are studied,including different types of soft steel dampers,vibration isolation bearings,shapes memory alloy dampers,buckling restraint braces between frame-type bridge piers and energy dissipation support with self-centering function.
