Condition assessement of a six-span full-scale bridge using forced vibration
Forced Vibration testing of four different damage states of a full scale, six span, reinforced concrete bridge, were conducted by Utah State University. These tests were performed to characterize the bridge based on its dynamic characteristics and to determine any correlation that may exist between the dynamic properties of a structure and the location of the inflicted damage. The test structure was a mature bridge being prepared for demolition as part of the Interstate 15 reconstruction through Salt Lake City. An eccentric mass shaker was utilized to excite the structure at several different natural frequencies for which data was collected through an array of seismometers. This data was processed to determine the natural frequencies and mode shapes of the structure. Investigation showed a decrease in the natural frequencies of the structure as well as noticeable changes in the mode shapes of the structure as a result of localized damage to the structure.
