Three ground motions were generated  by matching the response spectrum of the site provided by the Earthquake Design Standard of  Thailand.  The  mechanical  behaviour  of  dam  materials,  such  as  rockfill,  clay  core,  random  and  filter,  was  described  using  Mohr-Coulomb  and  Hardening  soil  model. Furthermore,  the  effect of the different modulus of elasticity is also included in this study. The frequency and  dynamic  analyses  were  conducted  and  the  overall  dam  behaviour  is  expressed  in  terms  of  first-four mode  frequency and  shape, displacement,  stress-strain and acceleration  fields. The  results  show  that  the  maximum  crest  settlement  is  104 cm  which  is  less  than  the  freeboard  length  provided  by  the  dam.  The  method  used  in  this  study  can  be  used  as  one  of  the  systematic  ways  to  evaluate  the  seismic  safety  of  operating  earth  dams  in  the  northern  Thailand.  aThesis (M.Eng.) - Asian Institute of Technology, 2010 0aEarth damsxEarthquake effectsxEvaluationzThailand, Northeastern0 aPennung Warnitchai,eChairperson1 aKyung-Ho Park, eExamination committee0 aSun Sayamipuk, eExamination committee0 aChayanon Hansapinyo, eExamination committee2 aRTG Fellowship, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
