Evaluation of seismic responses of an arch dam under non-uniform ground motion using random vibration [PDF]
Journal of Structural and Construction Engineering, 2020 To investigate the seismic responses of dams due to ground non uniform displacements, the records of earthquake displacements are required. Such data is seldom recorded during a specific earthquake and in the most cases the recorded data in not ...

Predicting Models for Local Sedimentary Basin Effect Using a Convolutional Neural Network
Applied Sciences, 2023 Although the numerical models can estimate the significant influence of local site conditions on the seismic propagation characteristics near the surface in many studies, they cannot feasibly predict the seismic ground motion amplification in regular ...
