Abstract: The modified Findley line is proposed by using ultimate strength and endurance limit as parameters to obtain a good initial approximation of an acceptable design. Comparing with experimental ...

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 describes a case study to quantify the behavior of precast, prestressed-concrete bridge girders made with high-strength concrete. As part of the case study, four bridge girders made with 77.2-MPa (11.2-ksi) ...

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 ...
