A simplified nonlinear coupled Newmark displacement model with degrading yield acceleration for seismic slope stability analysis

The use of Newmark permanent displacement to preliminarily evaluate the seismic performance of earth slopes has been well accepted in geotechnical community. Essentially, the seismic displacement would cause slope soil shear strength to reduce, thus causing the slope yield acceleration to degrade du...
