Abstract:
Presents a simplified approach to the design of single span or continuous multiple span moderate length (300 ft [91 m]) integral concrete bridges. The bridges envisioned have embankment and pile supported shallow stub-type integral abutments. For multiple span bridges, piers are either of a flexible type attached to the superstructure, or a semi-rigid self-supporting type with movable bearings. Application of this simplified design approach will produce cost-effective, durable, integral bridges, and will enable expeditious modification or replacement of many thousands of deficient or structurally obsolete bridges now burdening the transportation system in the United States.
