Fatigue Assessment of Prestressed Concrete Slab-Between-Girder Bridges

Prestressed Concrete Girder Bridges Using Large 0.7 Inch Strands

The National Bridge Inventory (NBI) includes more than 600,000 bridges within the United States of Prestressed concrete girder bridges represent one of the most widely used bridge systems. The majority of these girder bridges were constructed using 0.5 and 0.6 inch diameter strands. The main impediments to using larger strand diameters are: 1) bed capacities, 2) lack of structural knowledge reg...

Optimization of Precast Prestressed Concrete Bridge Girder Systems

60 A practical approach to the optimal design of precast, prestressed concrete highway bridge girder systems is presented. The approach aims at standardizing the optimal design of bridge systems, as opposed to standardizing girder sections. Structural system optimization is shown to be more relevant than conventional girder optimization for an arbitrarily chosen structural system. Bridge system...
