Service Life Extension of Early Age Steel Bridges by Reducing Dead Weight
Steel bridges from the beginning of last century are riveted structures, the material properties corresponding to present mild steel, although the main characteristics show large dispersion. Hence, the assessment of the load carrying capacity should be based on rather low values of the yield stress. Careful analysis, supplemented by a limited number of material tests has shown that in its present state, a portal frame steel bridge in Ghent is able to resist the load of limited urban traffic, tramways and buses. However, due to the installation of a heavy concrete tramway rail slab, unity checks are no longer satisfied. It is demonstrated that for portal frames, reduction of the dead load can be a solution to increase the load carrying capacity and thus the service life of the bridge.
