Abstract:This study examined the dynamic behavior of two-column bents used to support box-girder bridges. Three 0.3-scale specimens were subjected to earthquake records from the 1994 Northridge Earthquake using a large shake table (4.3 x 4.4 m [14 ft x 14 ft 6 in.] in plan) at the University of Nevada, Reno. Details in the bents were based on the 1999 California Department of Transportation design standards. The specimens were identical except for the column aspect ratios, which were 2.5, 4.5, and 6.64. Experimental data were collected at the critical sections in each specimen. The three specimens successfully resisted high levels of seismic loadings and achieved sufficient ductilities. The observed and measured results of the three specimens were helpful in understanding dynamic behavior and are documented in this paper.
