Short-span railway composite bridges: test and rating

Abstract eng:
This paper presents an overview of the in–service performance assessments of a steel–concrete composite (SCC) short–span railway bridge superstructure. A field load testing and visual inspections for the assessments of the SCC bridge durability under an actual service environment were conducted. The test result indicates that the SCC bridge superstructure has no structural problems and is structurally performing well in–service as expected. The results may provide a baseline data for future field SCC bridge load bearing capacity assessments and also serve as part of a long–term performance of SCC bridge superstructure.
