"FP" prestressed bridge beams have been
invented since 1995 by Pont-TERV Engineering
Consultants and the manufacturer FERROBETON Ltd. The
beams cover the 2-14 m clear span range of bridges.
The prestressed beams are designed to meet mainly
the requirements of the road bridges, but they are
suitable for the construction of pedestrian bridges,
and for other engineering structures of the
hydraulic engineering or the building construction
as well. The bridge beams are approved by the
Authorities (Road Administration Licence No.:
The superstructures of the
FP-type road bridges consist of beams close to each
other and a cast in situ R.C. slab on top of them.
The composite action between the girders and the
slab is provided by stirrups. The system is suitable
for the construction of simply supported or
multispan bridges of different width and skew angle.
These superstructures have
the advantages both of the prefabricated and the
cast in situ structures (quick construction without
scaffolding, compact bottom slab surface without
gaps, reduced structural depth). The precast outer
surfaces are aesthetic, resistant against corosion
what also results in reduced maintenance costs.
The bridge beam family consists of three types:
20 cm deep girder for 2,00 - 5,00 m clear
30 cm deep girder for 6,00 - 12,00 m clear
37 cm deep girder for 9,00 - 14,00 m clear
