A shaking tables test considering multi-support excitation was conducted on the 1∶10 scale three-span rigid-framed bridge. Taking the results of the test as a base, the finite element model of the bridge was established. Ten typical near-fault ground motions were selected for analysis. Then, the comparative analysis of the dynamic responses between the far-field ground motions and near-fault ground motions was completed. The research showed that the spatial effect of ground motion was unfavorable to the deformation and stress of piers, and its influence was closely related to the constraint forms of piers and girders and the wave velocity. Compared with the far-field ground motion, the aPGV/aPGA of the near-fault ground motion was larger. Considering the near-fault effect, the deformation and stress of the piers increased, and the mid-span bending moment and horizontal displacement of the main girders also increased. Therefore, near-fault effect and ground motion spatial effect should be considered in seismic design to make the analysis results more accurate.
