摘要
金属耗能器是利用金属不同形式的弹塑性滞回变形来消耗能量。近年来,国内外研究开发了许多不同类型的金属耗能器,其中一些类型的金属滞回耗能器已在新建建筑和抗震加固工程中得到应用。本文介绍了几种应用较为广泛的新型金属耗能器的原理、构造、性能以及在实际工程的应用,并提出了今后需进一步研究解决的问题。
Metallic dampers utilize the metal elastic-plastic hysteretic deformation to disgipate the energy. In recent years many different types of metallic dampers have been made and developed in China and abroad, Some types of them are applied in new building and seismic retrofitting of structure. This paper introduces several types of metallic dampers, including their principles, configurations, characteristics and engineering applications. In addition, several problems need further researches are proposed.
