Deformation and Energy?Based Seismic Damage Model of Reinforced Concrete Bridge Piers
Translated Abstract
A seismic damage model is established considering the combination of normalized plastic deforma-tion and hysteretic energy dissipation.On the basis of experimental results collected,the limit values of the damage index in each pier were calculated at different performance levels.The probability distribution and characteristic values of the damage index were obtained by probability analysis.It is suggested that the damage index has a value of 0 at the beginning of yielding and a value of 1 at failure,and the non?convergence problem existed in the Park?Ang damage index can be solved.The scatter of the damage index at different performance levels is significantly reduced by comparison with the Park?Ang damage index.
