DESIGN OF CONTINUOUS HIGHWAY BRIDGES WITH PRECAST, PRESTRESSED CONCRETE GIRDERS Clifford L. Freyermuth Design Research Section Portland Cement Association Skokie, Illinois Continuous highway bridges with precast, prestressed girders have been built by a number of states.

Examples of bridges of this type built by the states of Tennessee and. concerned with the design and performance of precast prestressed bridge girders made continuous. The design and construction of bridges composed of simple-span, pretensioned girders made continuous for composite dead loads and for live loads has become widespread.

In general, the design of these structures has been based on the procedures. These girders are characterized by 5 inch thick webs and are prestressed with both harped and straight 1/2 inch diameter grade strands.

Previous research had recommended the elimination of endblocks for simple span bridges. This study dealt with continuous bridges. The research consisted of a field test and a destructive laboratory test. entitled “Design of Continuous Highway Bridges with Precast, Prestressed Concrete Girders” published by the Portland Cement Association (PCA) in August The distance from the composite neutral axis to the bottom of the beam is in.

Volume 1: Literature Review and Preliminary Designs. The Texas Department of Transportation (TxDOT) is currently designing typical highway bridge structures as simply supported using standard precast, pretensioned girders.

With respect to the question on continuity, 50% design precast-prestressed concrete girder bridges as simple spans for all loads.

Sensitivity Study. Slab-on-girder systems composed of a cast-in-place concrete deck on Washington State DOT precast prestressed concrete wide flange (WSDOT WF) I-girders were studied. A number of prestressed concrete I-girder bridges built in the past several decades have demonstrated the ability of precast, prestressed spliced girder bridges to compete with structural steel plate girder bridges in the ft - ft span range.

Some states limit the maximum transportable length of a member to ft and the weight to 70 tons.
