Shear Behavior of Ultrahigh-Performance Concrete Pretensioned Bridge Girders

Precast, Pretensioned, Post-Tensioned Concrete for Bridge Decks

The problem of concrete bridge deck deterioration on many of our newer as well as older bridges is severe, somewhat perplexing as to cause, and difficult to solve. Furthermore, the cost to highway agencies for their repair, and the cost of delay to the highway user, can be extremely large. The use of precast, prestressed concrete for bridge decks is a con­ cept of construction or reconstruction...

Shear Strengthening Using Cfrp Sheets for Prestressed Concrete Bridge Girders in Manitoba, Canada

Effects of Temperature Variations on Precast, Prestressed Concrete Bridge Girders

The monitoring of a precast, prestressed girder bridge during fabrication and service provided the opportunity to observe temperature variations and to evaluate the accuracy of calculated strains and cambers. The use of high curing temperatures during fabrication affects the level of prestress because the strand length is fixed during the heating, the coefficients of thermal expansion of steel ...
