Depending on the location, highway bridges can often support considerable amounts of traffic. Due to the limitations on current earthquake forecasting techniques, a normal amount of traffic will also typically remain on a bridge when an earthquake occurs. In addition to traffic, scour effects are also a potential hazard to bridge piers that may simultaneously impact the structural integrity of the bridge together with seismic loads. Although a few studies investigating the combined effect of extreme and service loads have been conducted on long-span bridges or in high-seismic zones, the studies on typical short- and medium-span bridges in low and moderate seismic zones are rare. A general dynamic simulation methodology is introduced to study the combined realistic service and extreme loads on short- and medium-span bridges. As the initial effort studied the bridge performance under multiple service and extreme loads, this study sheds some light on more comprehensive studies for the future.
