Spliced Girders

Dolan, Charles W. / Hamilton, H. R. (Trey)

Abstract 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. Safety requirements and higher traffic volume have caused increased bridge span length requirements to accommodate additional lanes or move abutments away from the road edge. Replacement bridges often keep the same structural profile to maintain traffic clearance and approach elevations. To increase span capacity, three strategies are employed: higher strength concrete, continuity, and girder splicing.
