Damage indices evaluation for seismic resistant structures subjected to low-cycle fatigue phenomena

Abstract

The study of damage accumulation has a relevant interest in predicting the life of aerospace structures or seismic resistant structures subjected to low-cycle fatigue phenomenon. Damage indices, based on a linear accumulation rule, are presented in this paper. Documented solutions and new proposals for stationary and non-stationary processes are discussed and their accuracy is proved with numerical simulation. These damage indices take into account the randomness of the input excitation applied to the structures. The evaluation of these damage indices requires the knowledge of the statistic of the response process. For a non-stationary process the statistics of the response is calculated through evolutionary power spectral density.
