Abstract
The paper describes the results of numerical analyses carried out for the assessment of the seismic behavior of the Menta Bituminous Faced Rockfill Dam, located in Italy. The computer code FLAC based on the finite difference method was used to build a numerical model using the standard input data provided in the framework of the 15th ICOLD International Benchmark Workshop on Numerical Analysis of Dams. The behavior of the rockfill material was modelled using an elasto-plastic constitutive model, taking into account the shear modulus reduction and the hysteretic damping caused by the development of cyclic shear strains in the dam body. Constitutive parameters for rockfill were calibrated using the available laboratory data. Dam seismic behavior with respect to the assigned input accelerograms was inspected; in particular, the seismic performance of the dam was assessed evaluating its response in terms of dam crest acceleration and displacements: the latter turned out to be relatively small at the selected shaking scenario. Finally, the dam seismic behavior was analyzed focusing also on the role of the temperature-dependent bituminous facing stiffness and the return period of the seismic input.
