Abstract: A regional bridge failure database was used to determine the bridge failure rate with associated causes. Using a sample population from one DOT over a 25-year period, the average number of bridge failures was approximately

Abstract: A curved, three-span continuous, steel I-girder bridge in Salt Lake City was tested in order to determine its dynamic and static load carrying properties for three boundary condition states. For each of the three boundary ...

Abstract: Seven forced vibration tests were performed on an isolated single span of a freeway overpass structure. The tests were performed in connection with a series of states of controlled damage and repair. The work focused on ...

Abstract: Vibrations of horizontal, variable-arc-length beams considering the effects of large initial static sag deflections due to self weight are investigated. The variability in beam arc length arises from one end being pinned, ...

Abstract: In the field of nondestructive evaluation and damage detection, there is continued interest in the utilization of vibrational techniques. Structural damage will result in permanent changes in the distribution of structural ...

Abstract: This paper presents an evaluation of flexural live-load distribution factors for cast-in-place box-girder bridges. The response of a typical box-girder bridge was recorded during a static live-load test. This test involved ...

Abstract: Very little data exists on the live-load behavior of twin-girder bridges despite their unique configuration and minimal redundancy. To investigate the live-load behavior of twin girder bridges, the State Highway 52 Bridge ...

Abstract: For the last 4 decades, concrete bridges have benefited from larger diameter prestressing strands, which have increased from 13 to 15 mm in diameter and are now the standard in the US. The largest commercially ...
