Stochastic Dynamic Analysis for High CFRD Considering Uncertainties of Material Parameters

Due to the uncertainty of the source of dam construction materials for CFRD, the material model parameters should be uncertain values, so the traditional deterministic seismic safety evaluation method is difficult to objectively evaluate the CFRD, especially difficult to analyze from the perspective of the probability of performance, and there are only a small number of studies that consider the effect of uncertainty in the dam construction materials, and there is virtually no literature to consider the effect of the randomness of elasticity-plasticity parameters of the dam construction materials on the seismic There are only a few studies considering the effect of uncertainty of dam construction materials, and almost no literature considering the effect of randomness of elastic–plastic parameters of dam construction materials on the seismic response, while the effect of parameter uncertainty on the seismic response of CFRD cannot be ignored.
