Situation

By utilizing staged construction, the Federal Road Office (ASTRA) is improving, in stages, the road safety for the Mositunnel and reconditions the road connection Brunnen south. The static verification showed that the access bridge from Brunnen to Sisikon must be strengthened to support torsion loading.

Solution

In regular intervals of 10.80 meters, massive steel crosses are set in the box girders. To accommodate the hoop tension, the box girder is wrapped with six layers of S&P C-Sheet 240 400 g/m2 (Modulus of elasticity 240 kN/mm2). The carbon sheets are engineered to provide a design tension capacity corresponding to a 0.6% elongation.

Material

Approximately 220 m2 S&P C-Sheet 240 400 g/m2
