Some applications on concrete segmental bridges

The technique of precast segmental construction is now 25 years old and has allowed many structures of unusual interest to be built throughout the world. The span by span method in moderate span lengths allows the economical and rapid construction of highway or mass transit repetitive bridges. Cable stayed spans now combine the use of precast segments with stay technology in a wide range of span lengths. In the future, the combination of concrete and steel in new types of composite structures will allow longer spans when cable stay techniques progressively replace conventional suspension bridges (a).
