Abstract

Seismic behavior of concrete faced rockfill dams (CFRDs) has not been sufficiently examined due to limited measured response in the field. This study presents results of numerical experiments (finite element analyses), which investigate effects of hysteretic damping and interface between rockfill and concrete face on the seismic behavior of CFRDs. The analyses use a recently developed, three-dimensional, distributed element plasticity soil model (I-soil) which allows flexible control over hysteretic behavior and can model both Masing and user-defined non-Masing type un/reloading. Numerical results are compared with centrifuge test data performed by others, including spectral response, and bending moment increments on the concrete face. The best estimates were obtained using non-Masing type un/reloading rules along with frictional interaction between concrete face and rockfill interface. These results suggest that the seismic response of CFRDs can be better simulated with proper characterization of hysteretic damping and interaction between different components of the dam body.
