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
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 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 • 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
