The objective of this research is to verify the code–specified girder distribution factors (GDF) for continuous steel girder bridges by field testing. it is found that the analysis results are not conservative, and in some instance, the analytical results underestimate the actual GDF’s, which can lead to a groundless notion of safety. As a result, it is found that GDF’s specified in AASHTO LRFD should be used with careful reservation.
