摘要
简要介绍了形状记忆合金(ＳＭＡ)材料的本构关系及其显著特性。总结了桥梁结构在地震和风振作用下的灾害,以及ＳＭＡ驱动器和阻尼器在桥梁结构隔震及减震应用上的研究现状,展望了ＳＭＡ在桥梁结构尤其是在大跨度斜拉桥和悬索桥结构抗震抗风振动控制中的应用前景,指出了基于ＳＭＡ材料的桥梁结构振动控制研究中亟待解决的一些关键技术。
In this paper, the constitutive relation and the unique properties of shape memory alloy (SMA) material are briefly introduced. Earthquake disaster and wind disaster of bridge are summarized, then a review of seismic isolation and mitigation of bridge structure by SMA actuator and damper is presented. Prospect about vibration control of bridges, especially of long-span cable-stayed bridges and cable-supported bridges by SMA is discussed, some critical technologies in the bridge vibration control by SMA are pointed out.
