This article presents the results of the analysis carried out to quantify the effect of topographic amplification, on the top of a hill of rock for different seismic records, verifying the significant increase in the accelerations recorded on slopes and peaks, compared to the valley area. The results obtained showed that there could be important variations in the magnitude of the amplification and main frequency of the seismic movement at the top of the hill, depending on the characteristics of the earthquake used and the predominant period of this, concluding that a bad selection of the earthquake could underestimate the response and designs associated with it. The earthquakes used correspond to two real records and one artificial record, which were scaled at the same acceleration in free field.© 2012 The Author(s)Conference Paper
