Influence of Prestress Degree to Long-Term Response of the Long Span Prestressed Concrete Bridges

Abstract:

Though the prestress degree that is selected under control of the specified stress limit is a key design parameter in design of the prestressed concrete bridges, study on long-term deformation of the long span prestressed concrete beam bridges is not popular both here and abroad. This paper reveals the time-dependent regularity of long-term stress and deformation effect to the critical sections of the long span prestressed bridges from various prestress degrees, thereby the necessity of stress and deformation control consideration during design of the long span prestressed bridge structures is verified, and the prestressing expression based on stress and deflection control for relative study and design reference is given.
