Seismic Slope Stability: A Comparison Study of Empirical Predictive Methods with the Finite Element Method
… incorporates a yield coefficient and the actual acceleration time history to estimate permanent displacements. Numerical methods incorporate advanced constitutive models to simulate the coupled stress-strain soil behavior, making the process computationally more costly. In this study, a model …

Dynamic soil modeling in site response and soil-large pile interaction analysis
… developed and calibrated using the displacement, acceleration, and pore water pressure time histories recorded in a free-field lateral spreading centrifuge test. The calibration process highlights the important role of small strain damping and the need for pressure-dependent dilation parameters to …

Seismic Response of Structures with Added Viscoelastic Dampers
… equations for earthquake motions described by acceleration time histories at discrete time points. For linear systems, we also develop a modal superposition method for this model of the damper. This superposition approach can be implemented to obtain the response time history for seismic input …

Shear Modulus Degradation of Liquefying Sand: Quantification and Modeling
… liquefied sand. The shear stresses and ground accelerations computed using this method reasonably matches those recorded at the Port Island Downhole Array (PIDA) site. The degrading shear modulus backbone method is recommended as a possible method for conducting ground response analyses at …
