Structural safety and compressive membrane action in transversely prestressed concrete bridge decks

Abstract:

This paper describes the research carried out to investigate the safety of transversely prestressed concrete bridge decks. Laboratory tests were performed on a 1:2 scale model of a bridge consisting of a thin, transversely prestressed concrete deck slab cast in-situ between the flanges of long prestressed concrete girders. TNO DIANA 9.4.4 tïnite element software was used to analyze the scale model nonlinearly. The theoretical analysis, considering the beneficial effects of compressive membrane action (CMA), showed an adequate safety margin against the Eurocode Load Model 1 design wheel load (CEN 2003) leading to the conclusion chat the existing transversely prestressed concrete bridge decks still have sufficient residual bearing (punching shear) capacity.
