Abstract: 

Damage indexes consider different aspects of structural response with the objective of producing a quantitative measure of structural damage. In this paper, damage indexes based on deformation, energy, modal parameters and low cycle fatigue behavior are investigated in order to find a correlation between their numerical values. Selected damage indexes are compared by applying them in the nonlinear analysis of various low rise steel frames subjected to a set of seven earthquake accelerograms corresponding to a specific soil condition. Correlations between various indexes have been presented graphically and approximate conversion formulas are also provided.
