Analysis and Comparison of Different Confined Concrete Models

Abstract:

Different confined concrete models and their influences on column lateral load-deformation relations are compared and studied in this paper. The analytical results show that models have remarkable discrepancies on the descending branch of constitutive curves, and these discrepancies are weakened in predicting of column lateral load-defromation curves due to eccentric compression of confined concrete.
