and ~2,60 m wide; the concrete web is 30,5 cm wide with a height of 70 cm. For the entire
three-spanned bridge with a total of six prefabricated mono-WIB girders only three rolled
girders HEM 600 were used.
The ½ HEM 600 and the steel dowels are obtained by cutting a regular HEM 600 rolled
profile according to a pre-established geometry (“Fig. 7”, “Fig. 8”, “Fig. 9”) with the ad-
equate technology in the factory. Only a low amount of outcuts result. Afterwards the girders
are brought to the factory, where the dowel reinforcement, the binding reinforcement and the
required carrying reinforcement are disposed (“Fig. 10”). High class concrete is poured in the
formwork and after hardening, the prefabricated girders are carried to the site. The prefabri-
cated girders can also be produced on site, near the infrastructure.
