摘要 结构阻尼特性识别一直是结构动力系统参数识别中的难点问题．本文分析了目前常用的几种识别结 构阻尼特性的方法,讨论了各自的特点,并结合数值模拟及实测信号分析比较了各自的识别效果． Structural damping has remained the least discernible parameter in the dynamic design of civil engineering structures. This paper reviews several commonly used techniques for damping estimation from a time history of response. Their effectiveness and limitation are then compared by numerical examples as well as filed measurements.
