The stiffening effect of existing features on historic truss bridges was examined. 3D analytical models as traditional skeleton structures were compared to models that included the bridge decks.
The analytical models were compared to field tests under real wind conditions. A methodology for use of stiffening elements such as decks is offered to aid engineers in historic bridge preservation efforts.
This research was made possible through Grant MT-2210-04-NC-12 from the National Center for Preservation Technology and Training (NCPTT).
