The instruments used to record the response of the bridge were strain gauges and dial indicators. This field test was divided into two stages: a concentrated force loading test on the prefabricated girder that settled on the bridge supports before the girders were connected transversely and a vehicle loading test after the girders were connected transversely. The response of the bridge was recorded during the field test. To study this diversity, this paper presents an evaluation of lateral load DFs for prefabricated hollow slab bridges.
The diversity between design and actual DFs may be varied as the bridge parameters changed.
Distribution factors (DFs) for one typical cross-section as specified in the AASHTO LRFD specification can be varied when the bridge parameters such as span length, loading lanes and skew are changed.
