• Abstract:
  The most common method used to design and analyze bridge decks, termed the traditional ; method, treats a deck slab as if it were made of strips supported by inflexible girders. An ; alternative – the empirical method – treats the deck slab as a unit that resists load primarily ; through internal arching action. The mechanics of the empirical method are more complex, but ; the design process is simpler, and it offers advantages in economy and constructability – e.g., ; the empirical method requires much less internal reinforcement. A few states allow the empirical ; method; however, in Florida, this method awaits ; verification testing for phased construction and ; widening situations before it can be allowed in the ; design guidelines. ; University of North Florida researchers tested the ; efficacy of the empirical method for bridge deck ; design, in a widening situation using a full-scale ; bridge deck and support structures.
