What Will We Be Reviewing?

  • Web resources  click here

  • Common types of bridges

    • Truss, suspension, cable stayed, solid ribbed arch, continuous spans, cantilever spans

  • Structural engineering terms

    • Compression, tension, shear, gusset plate, deck, strut, tie, footing, camber, truss, live load

  • Strength to weight ratio

    • Means of determining structural efficiency






Bridge vocabulary l.jpg
BridgeVocabulary

  • CompressionStress characterized

    by pressing together.

  • TensionStress characterized by pulling apart.

  • ShearStress placed transversely on a member in opposite directions.

Bridge Vocabulary

  • Gusset plateA metal plate used to unite multiple structural members of a truss.

  • DeckThe top surface of a bridge which carries the traffic.

  • StrutA compressive member.

  • TieA tension member of a truss.


Bridge vocabulary9 l.jpg
Bridge Vocabulary

FootingThe enlarged lower portion of the substructure or foundation which rests directly on the soil, bedrock, or piles; usually below grade and not visible.

  • CamberA positive, upward curve built into a beam which compensates for some of the vertical load and anticipated deflection.

Bridge Vocabulary

  • TrussA structural form which is used in the same way as a beam, but because it is made of an web-like assembly of smaller members it can be made longer, deeper, and therefore, stronger than a beam or girder while being lighter than a beam of similar dimensions.

  • Live loadThe dynamic or moving weight, such as traffic, carried by a structure.


Strength to weight ratio l.jpg
Strength to Weight Ratio

  • A measure of the efficiency of a structure

    • Normally associated with bridges

  • Compares the weight of the structure to the amount of weight it can carry or support without collapsing

Strength to weight ratio:

supported weight / structure weight
