Abstract:

Through a review of existing field inspection results and bridge details, many bridges have been identified as susceptible to out-of-plane, distortion-induced fatigue cracking. The review includes floor beam girder, multiple-girder diaphragm, and floor beam tie girder box systems. Consideration is given to primary live-load stresses on the global scale, whereas live-load stress ranges, rotations, and out-of-plane distortions are investigated at the local level. The details of plate attachment, the manner of force transmittal between components, and the specific geometry at gaps are shown to be influential factors in determining the magnitude of out-of-plane distortions and corresponding stresses. Cases are cited in which secondary members imposing out-of-plane displacements of only thousandths of an inch have resulted in cyclic bending stresses at the level of allowable stresses at details. Specific behavior for each detail is discussed.
