The resulting seismic action on bridge is characterized by an important pulse type motion that is not considered in many international structural designed codes. In this paper, the effects of near-fault ground motions applied on regular highway bridges with design parameters selected by a sampling method, are discussed and compared with the ones of the same bridges subjected to far-fault earthquakes. Time history analyses were performed on fiber element bridge models by means of OpenSees considering seven near-fault earthquake input records with significant velocity pulse selected worldwide from the PEER database considering the same site conditions, and the El-centro earthquake record as ordinary far-field earthquake. The results are analyzed in term of top pier drift ratio, pier slenderness ratio, PGA and earthquake intensity parameters.
