Abstract: This paper presents experimental and analytical results of four scaled prestressed concrete box-girder bridges with corrugated steel webs.
The location of prestressing strands at both ends of the specimens and the thickness of end diaphragms are the two major parameters.
Based on the experimental results of all four specimens, their seismic behavior is critically examined, including hysteretic loops, ductility factor, dissipated energy, and failure mode, etc.
It was found that both the thickness of end diaphragms and the location of prestressing strands at both ends of the specimens are insignificant when the specimens failed at the mid-span due to concrete crushing, and the proposed analytical model can be used to predict the load-displacement relationship of such bridges.
