In the early 2000s, a prefabricated composite girder (VFT-WIB technology) using T-beams, which was cut from an I-beam web in a corrugated shape, was developed in Germany. The first bridge to which this solution was applied was completed in 2004. Initially, this solution was applied with puzzle-shaped shear dowels. In recent years, the number of prefabricated hybrid bridges using clothoid-shape shear dowels with improved cut shape has been increasing in European countries, especially Poland.
The design shear strength formula of the clothoid-shape shear dowels and its calculation example are shown in this paper. In addition, the recent hybrid bridges using clothoid-shape shear dowels constructed in Poland are reported.
