Spliced Girders SpringerLink

2018-11-15  Precast, prestressed girders are widely used in buildings and bridges; however, one of their main limitations is the length of the span that can be shipped or the capacity of a simple span beam. AASHTO girder standards were established a half century ago.

16. Abstract The Texas Department of Transportation designs typical highway bridge structures as simple span systems using standard precast, pretensioned girders. Spans are limited to about 150 ft due to weight and length restrictions on transporting the precast girder units from the prestressing plant to the bridge site. Such bridge construction, while economical from an initial cost point-of ...
