The final article in this series examines the long-term management of concrete bridges. The inspection and assessment of a bridge over its entire life, the maintenance requirements and possible strengthening to upgrade the bridge to a new load configuration or revised layout are discussed.
This article examines the detailing that is particular to a concrete bridge. All details need to consider buildability, durability and maintainability, as well as safety and aesthetic issues.
This article examines the prestressing for a concrete bridge. Prestressing enhances the capacity of a member that is weak in tension, but strong in compression. It effectively creates a new material that is strong in tension. A prestressed bridge has much less steel to be handled, which reduces congestion, leading to easier and quicker concrete placing.
