Abstract
In this paper, seismic performance reliability of reinforced concrete (RC) structures was evaluated based on response surface method using a systemic approach. In the systemic approach, limit state functions were applied at the structural component level and structure performance reliability index was calculated with a systemic approach through series and parallel combinations of structural components. The limit state functions were estimated through improved response surface method based on block sampling design of random variables. Numerical studies showed that the proposed systemic approach could calculate performance reliability indices at different damage levels from structural components while only one reliability index was evaluated through the overall approach for the given performance levels. The results indicated that performance reliability indices increased when the non-performance scenarios were examined for high levels of components damage, and performance reliability indices of the overall approach corresponded to an interval including levels 2 and 3 of the systemic approach.
