Abstract:
Until 1979, highway bridges in Ontario, Canada, were designed to the American Association of State Highway and Transportation Official (AASHTO) specifications, which required the deck slabs to be considered in pure bending. The term deck slab is used in this article to describe the concrete slabs of girder bridges. Extensive research sponsored by the Ministry of Transportation of Ontario (MTO), Canada, and conducted with the help of both laboratory models and field testing of bridges has confirmed that deck slabs, because of an internal arching action, are much stronger than slabs in pure bending. This research also confirmed that the amount of steel reinforcement in deck slabs can be reduced considerably by taking into account the internal arching action.
