Concrete Bridge Design & Construction series

This series, authored by the Concrete Bridge Development Group (CBDG), summarises all the key areas concerning concrete bridge design and construction.

The CBDG aims to promote excellence in the design, construction and management of concrete bridges. With a membership that includes owners, designers, academics, contractors and suppliers, it provides a focus for the use of best practice, innovation, training initiatives and research and development.

The series was published between January and December 2014.

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.

The Structural Engineer

This article examines the selection process for the most suitable type of concrete bridge. The general parameters of the scheme such as typical spans, overall deck area, clearance requirements, alignment and the overall aesthetic will start to suggest which type of bridge deck and construction methods might be appropriate.

The Structural Engineer

In this article, the various types of formwork and falsework needed to construct a concrete bridge are examined. The choice of bridge type depends not only on the general parameters of the scheme (such as typical spans, overall deck area, clearance requirements, alignment and the overall aesthetic), but also on the particular and local parameters of the site, many of which are related to construction.

In situ options tend to be used on projects where the speed of construction is not critical, or where the lower costs of the in situ works justify a slightly longer programme.

This month’s article from the CBDG’s Technical Committee examines the construction methods for the six basic types of precast concrete bridge: • Standard precast inverted T/Y, I or U beams • Bespoke precast T, I or U beams • Precast segmental box girders with short segments • Whole span precast box girders • Incrementally launched box girders • Modular precast system with short shell segments

The various high performance concretes that might be used for concrete bridges, to make them either quicker and easier to build, or more economic are discussed. The advantages of high strength, lightweight, fibre reinforced and self-compacting concretes are described, together with the use of new materials that can replace steel for both reinforcement and prestressing.
