| Summary: | (1992). Many existing details resemble those currently analysis method was used in order to obtain the SCF for each attachment intersecting a transverse stiffener is an example been the subject of recent research projects are specified in can also lead to large restraint forces in the weld region, come close together and the SCF for each weld toe covered by specification, but closer inspection of these detail. The SCF for each coped detail was compared to that details reveals inherent differences. A coped longitudinal different intersection geometries, the finite element stress fatigue strength of the detail when compared to a slightly for many of the welded details that are typically used in highway bridge construction, only those details which have However, depending on the size of the cope and thickness larger cope size. As the cope size is reduced, the two welds made. The cope in the longitudinal plate should not be of a base model with no cope. The non coped model signifies of such a detail. In order to measure the severity of of the cope detail was determined by the relationship of its parameters for this investigation were gusset plate width, plate. From this investigation several conclusions could be possible category for a detail with a cope is Category D. ratio between the plate and web, this category can be reduced SCF for a Category C detail was also obtained. The severity SCF to the SCF of the Category C and E detail. The studied size of the cope, and the thickness of the gusset and web size, and thickness ratio. smaller than one inch. Smaller gap sizes can reduce the superimposed on each other. The close proximity of the weld the AASHTO fatigue category for a given plate width, cope the AASHTO Standard Specifications for Highway Bridges the SCF that correlates to an AASHTO Category E detail. The to Category E. An equation was developed that would predict which also reduces the detail's fatigue strength. The best While the NCBRP program has evaluated the fatigue strength |
