Inspection and repair of the M56 Thorley Lane post-tensioned bridge

This paper discusses situations where the shear connection in a composite beam of steel and concrete can be subjected to concentrations of shear flow as well as relevant finite element analyses.

This article covers technical and asset management aspects related to the assessment and subsequent strengthening design for post-tensioned concrete box-girder bridges.

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.
