A Damage Model for Reinforced Concrete

Document Type: Proceeding Paper

Part of: Seismic Engineering: Research and Practice

Abstract:

The damage index developed by the authors models concrete damage as a low-cycle fatigue phenomenon. By quantifying the energy dissipated as a fraction of the total energy dissipation capacity, the model simulates both the residual strength and stiffness and capacity to resist further loading. Coupled with the authors' hysteresis model for RC frame members subjected to cyclic loading, it is capable of accurately reproducing experimental load-deformation curves, including the strength and stiffness degradation observed in such experiments. Thus the model is suitable for seismic risk evaluations of RC buildings damaged by strong earthquake ground motions.
