Temperature variations in concrete bridges
Web9.1.1.A Concrete Bridges Semi-integral design is used for prestressed concrete girder bridges under 450 feet long and for post-tensioned spliced concrete girder and cast-in-place post-tensioned concrete box girder bridges under 400 feet long. Use L-type abutments with expansion joints at the bridge ends where bridge length exceeds these values. Web2 Mar 2024 · For concrete bridges, the temperature gradient model of the Canadian CSA-S6-00 (Canadian Standards Association International CSA, 2000) is constant along the top 0.4 m of the depth, followed by a linear stage along the following 0.6 m and end with a second constant region of temperature gradient extend to a depth of 2.0 m.
