Integral bridge using the VFT-WIB technology for a three-spanned structure - Economical Bridge Solutions based on Innovative Composite Dowels and Integrated Abutments - page 128

The bridge is located in the village Frânceşti and crosses over the Bistriţa River. The ex-
isting bridge is a provisory structure (“Fig. 1”), not ensuring the safety of its passengers, with
a total length of 75,00 m, having 10 spans each of approximately 7,50 m length and a width of
2,40 m. It is the only crossing possibility of the river for the local communities and in urgent
need of renewal. Bridges are one of the main founds consumers and an important investment
for a small community. The economical factor is important in terms of material consumption,
environmental impact and structure costs. Efficient solutions have to be elaborated in order
for the structures to be both durable and economic.

The replacing structure was designed as a three-spanned integral bridge with VFT-WIB ®
superstructure. Each span has a length of 21,10 m, with a total length of 64,50 m, the width
is 5,20 m, with a carriageway of 4,00 m (“Fig. 2”). The design is based on the experience
gained at the Vigaun road bridge over ÖBB track Salzburg - Wörgl at km 23,135, Germany
built in 2008 [4].
