TL;DR: In this article, the authors investigated the application of the Endurance Time (ET) method in linear seismic analysis of structures and concluded that the ET method can be considered as an alternative time-history based analysis in the linear range.

TL;DR: 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, and the relationship between various indexes have been presented graphically and approximate conversion formulas are also provided.
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.
