AASHTO LRFD Concrete Slab and Wall design spreadsheet
AASHTO 2004 LRFD SLAB DESIGN: This spreadsheet was created to aid in the rapid design and/or checking of Bridge Decks or Reinforced Concrete Boxes in accordance with AASHTO 2004 LRFD. The 2nd Bar layer is particularly handy for different bar sizes used in the same layer, such as in Bridge Deck Cantilevers.
