The embankment-subsoil subjected to multidirectional seismic loading simultaneously-prediction of strain mechanism

Abstract

The limitation of research in using numerical simulation is related to simulate boundary condition and application of seismic load in the multidirectional to the model. The nonlinear loading is applied in one direction which is horizontal direction was presented in several kinds of literature. In the simulated, a model is subjected to the seismic loading needs to apply near-fault ground motions on multidirectional simultaneously for the prediction of the straining mechanism. In this study, by using nonlinear finite element software, the strain and stress were analyzed when the near-fault ground motion was applied to the embankment-subsoil model in a single direction and multidirectional. To control the quality of the numerical simulation the statistical analysis was applied. The maximum stress-strain results of the several stages of numerical simulation pulled out for statistical analysis and prediction of the strain-stress density mechanism. According to the statistical analysis, the results reveal the apply multidirectional seismic loading to the embankment-subsoil model has better results quality. The outcome of this study enhances the quality of numerical simulation and prediction of the embankment-subsoil model seismic response. The method is presented in this study can apply to several engineering problems in which they are subjected to the nonlinear and linear dynamic loads in multidirectional simultaneous.
