In this paper a case study on ground response analysis of a seismic geotechnical site response analysis on Damghan earth dam in Semnan province of Iran during the Kahak earthquake (Ml5.7, 2007) after the magnitude-scaling factor is presented. For site characterization, deep site investigations have been undertaken and the nonlinearity on site response for the selected site with assumption of elastic and rigid half space bedrock by use of nonlinear standard hyperbolic model was evaluated. The modeling was implemented using the combination of several computer codes with MATLAB programming tool and their results over a number of geotechnical areas were compared to each other. The key factor in this work was to develop and use ˇ°Abbas Converterˇ± and the present research shows its ability on site response analyses procedure. %K Abbas Converter %K Kahak Earthquake %K Damghan Earth Dam %U http://article.sapub.org/10.5923.j.jce.20120201.01.html
