In the design phase, seismic ground displacements are usually assumed to be uniform between the structure supports. However, this is not necessarily the case for extended structures, such as bridges, especially when there are different soil and/or topographic conditions along the structure. In the present study, the response of an 850m continuous bridge located in a seismic region of PGA=0.1g, is investigated. A set of synthetic accelerograms is generated from 1D site-response analysis at each bridge support. Furthermore, a number of linear time-history analyses are performed, with and without uniform support excitation, in order to quantify its influence on the bridge performance.
