This paper discusses portions of a study utilizing the strong motion data obtained from twenty sensors on and near the Painter Street
Overcrossing in Rio Dell, California. Particular attention is paid to the influence abutment behavior has on measured response in the
three directions of motion of the bridge superstructure. Previous studies have shown that transverse modes of vibration predicted by
ambient testing may not reflect behavior during seismic events. The study also focuses on the influence of direction of input boundary
motions to be used in analytical models to predict bridge response.
