Box 416, Iran Azad Yazdani Department of Civil Engineering, University of Kurdistan, Sanandaj, P.O. Box 416, Iran Journal Article 2016 01 21 A procedure for updating the Park-Ang damage index of reinforced concrete building under near-fault ground motion is proposed. Rather than developing a new damage model, a correction term is added to the existing damage model within the Bayesian framework. The correction term is described as a linear function of the variation of stiffness of structures which is a more consistent indicator in predicting the level of damage. The Bayesian method is an effective approach when new data become available. The reinforced concrete building damage data during past near-fault pulse-like earthquakes were used in updating the damage model. The proposed damage index is conceptually simple and realistic. https://scientiairanica.sharif.edu/article_4188_99ab1aaed7a7191697cbd9c8e24d819f.pdf
