Abstract: A series of diagnostic tests were performed on three short‐span, two‐lane, steel‐girder bridges. Tests were performed with stationary and moving test trucks placed on the bridges one at a time and side by side. Wheel‐load ...

Abstract: Many multigirder steel bridges built before 1985 are experiencing distortion-induced fatigue cracking at diaphragm-girder connections. Fatigue cracks in the welds and base metal in hundreds of diaphragm-girder connections ...

Abstract: Many multigirder steel bridges built before 1985 are experiencing distortion-induced fatigue cracking at diaphragm-girder connections. A means of eliminating the cyclic stresses that cause those fatigue problems is to ...

Abstract: Many multigirder steel bridges built before 1985 are experiencing distortion-induced fatigue cracking at diaphragm-girder connections. In bridges in Birmingham, Ala. fatigue cracks in the welds and base metal in hundreds ...

Abstract: Many reinforced concrete bridges throughout the United States on county and state highway systems are deteriorated and/or distressed to such a degree that structural strengthening of the bridge or reducing the allowable ...
