Abstract

In light of the global water crisis and dams' role as water conservation superstructures for agricultural and domestic uses, this research 
assesses Pine Flat Dam's seismic performance when subjected to the vertical component of near-field earthquakes. In order to account for 
the impacts of foundation flexibility and hydrodynamic forces, the dam is modeled in the plane strain space under the foundation-structure- 
fluid interaction using Abaqus finite element software. The reservoir is simulated at three different levels of filling: full, half-full, and empty. 
The research shows that when the dam is operational, the full reservoir volume is filled with water, and near-field earthquake conditions 
prevail, greater displacement is applied to the dam, which might cause it to enter the nonlinear area..
