Abstract A finite element model of a bridge that considers the nonlinear mechanical behavior of piers was built using a reinforced concrete continuous girder bridge in an expressway as the subject. Comparative analysis via nonlinear time history integration was conducted to determine the influences of frequency characteristics, peak ground acceleration (PGA), and effective duration on the magnitude and distribution of hysteretic energy and structural damage under selected typical near-fault and far-field earthquake records. The following conclusions were drawn from the result:(1)The frequency characteristics of ground motion significantly influenced the seismic response of the bridge structure, and an increase in peak ground acceleration/PGA would obviously increase hysteretic energy and damage; (2) The hysteretic energy and damage of the bridge piers under near-fault earthquakes were greater than those under far-field earthquakes at the same PGA and duration, and the position of damage was considerably higher; (3) The proportions of hysteretic energy and damage under near-fault earthquakes were less than those under far-field earthquakes in certain regions near the pier bottom, whereas the aforementioned indices were contrary outside that region; this finding showed that hysteretic energy and damage under near-fault earthquakes were well-distributed along the piers. The comparative analysis indicated that near-fault earthquakes had higher energy and damage dissipation requirements than far-field earthquakes, and that such requirements increased upward along the pier. Consequently, strict measures for the seismic design of bridges under this type of earthquake should be proposed.
