摘　　要：采用金属耗能器进行结构抗震加固是一种较经济、简单、又可靠的耗能减震加固方法。本文介绍了几种常用金属耗能器的构造、原理与性能及其在建筑、桥梁抗震加固工程中应用的概况,给出了典型工程实例,并提出了金属耗能器在加固工程应用中应解决的一些问题。Structural seismic strengthening adopting with metallic dampers has been proven to be a cost-effective, simple and reliable method. Several types of metallic dampers are introduced in this paper, including their configurations, principles, characteristics, and the survey of seismic strengthening engineering application to buildings and bridges. In addition, some typical engineering examples are also presented. Finally, some problems which need to be solved in the future are proposed.
