Concrete Bridge Design and Construction. No. 4: Types of concrete bridge

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.

This second article from the Concrete Bridge Development Group's technical committee, examines the initial parameters that might determine the best layout for a new bridge.

This article from the CBDG's Technical Committee examines the construction methods for the six basic types of precast concrete bridge.
