Title: Designing for Continuity in Prestressed Concree Structures

Abstract:The design of simply supported prestressed members has been well estab-lished but the design of continuous prestressed concrete structures has received little attention because of difficulty in analyzing such members. A method of analysis is developed for contmuous prestressed members that reduces the problem to the same simplicity of analysis by moment distribution as for ordinary continuous reinforced concrete members. The method is relatively simple and does not involve abstract integrations of complicated expressions. The problem of design is simplified to the extent that a physical relationship can be seen between the profile of the curved wires and the forces they exert on the structure. Because the stresses pro-duced by these forces can be readily determined, the method of analysis offers greater flexibility in the design of continuous prestressed structures.
