Enhanced Camber Calculations for Prestressed Concrete Bridge Girders
| 项目名称： | Enhanced Camber Calculations for Prestressed Concrete Bridge Girders |
| 摘要： | Like many State Departments of Transportation, Missouri Department of Transportation (MoDOT) has been utilizing prestressed concrete I-girders in bridge construction for quite some time. Similarly, like other DOTs, MoDOT has observed issues of late with increased occurrences of negative camber in completed prestressed concrete bridges. Positive bridge camber in prestressed concrete I-girders is a critical design component in the ride, appearance, maintenance requirements and overall life of a concrete superstructure bridge. There are a variety of components that go into the final camber of prestressed concrete girders, including the initial calculation, casting and release, shipping and eventual loading with the deck components. MoDOT is actively exploring new ways to improve the efficiency, constructability and overall performance of bridge replacements and new construction. An enhanced girder camber calculation, taking into account many different factors and lessons learned over the years, will be a primary deliverable from this project. |
