Remaining Useful Life (RUL) refers to the length of time a structure can be safely used after an earthquake. Given that seismic resistance may be reduced due to damage, defining a damage index to assess post-earthquake performance is essential. This study proposes an efficient method for calculating the RUL of simply supported steel beams. To achieve this, various damage states of these beams were modeled, and both modal and pushover analyses were conducted to extract parameters such as natural period and target displacement at the life safety performance level. Using probabilistic seismic hazard models and attenuation relationships, the RUL of these elements was estimated. The extracted data were then used to train a supervised artificial neural network to develop a numerical model for estimating the RUL of similar beams. The results demonstrate the effectiveness of the proposed method in accurately predicting the RUL of simply supported beams. It should be noted that this study has limitations, such as simplifications in numerical modeling, exclusion of complex nonlinear material behavior, and challenges in generalizing the method to other structural components. Therefore, caution is advised when interpreting and applying the findings.
