Abstract – In this project three dimensional soil column model imposed to seismic loading has been analyzed with the help of Open System for Earthquake Engineering Simulation (Open SEES). The Open SEES is developed by PEER (Pacific Earthquake Engineering Research). In this analysis soil to soil pressure (Effective Stress), excess pore water generation (pressure exerted by water which is present inside the voids), dissipation of pore water pressure, settlement were investigated. To impose the seismic loading the three past real time earthquakes are taken such as Imperial Valley (Mexico), Tabas (Iran), and Valdivia (Chile). The Peak Ground Acceleration (PGA) for these seismic loading are 0.57g, 1.0g, 0.31g respectively. The time period for ground acceleration has been considered as 20 sec, 25 sec and 20 sec respectively. The effective pressure, pore water pressure, settlement are investigated from the results.

KeywordsPore Water Pressure, OPEN SEES, Peak Ground Acceleration
