RESOLVING RESTRAINT MOMENTS: DESIGNING FOR CONTINUITY IN PRECAST PRESTRESSED CONCRETE GIRDER BRIDGES

Analytical studies of Washington State Department of Transportation (WSDOT) of standard precast prestressed concrete bridge girders are presented. The paper's goal is to encourage engineers to design for continuity for superimposed loads and to demonstrate those occurrences where continuity design is most advantageous. To demonstrate the maximum possible economic advantages of continuity, a set of design examples will be provided comparing simple spans with continuous spans that neglect the effect of restraint moments. The paper demonstrates that under certain conditions, the effect of restraint moments can be small, and, therefore, significant economic savings due to continuity design can be achieved.
