介绍了一种新的局部损伤指标，其中所有的变形机制（弯曲，剪切，锚固滑移）引起的恶化分别为每一个机制。此外，从三个响应机制所产生的损伤的加性特征，以及它们的相互作用所造成的降解速率的增加，被充分考虑。建议的局部损伤指数，然后应用，与作者以前开发的有限元模型，以评估地震损伤反应的几个RC柱和框架测试样本与不合标准的详细说明。它的结论是，在所有情况下，独立于流行的失败模式，新的局部损伤指数描述以及分析标本的损伤模式。版权所有© 2012约翰威利父子有限公司.
A new local damage index for existing RC structures is introduced, wherein deterioration caused by all deformation mechanisms (flexure, shear, anchorage slip) is treated separately for each mechanism. Moreover, the additive character of damage arising from the three response mechanisms, and the increase in degradation rate caused by their interaction, are fully taken into consideration. The proposed local damage index is then applied, in conjunction with a finite element model developed previously by the authors, to assess seismic damage response of several RC column and frame test specimens with substandard detailing. It is concluded that in all cases and independently from the prevailing mode of failure, the new local damage index describes well the damage pattern of the analysed specimens.
