| Description
| - The basic specific property of the weathering steel is its ability to create a protective patina layer on the surface, if suitable atmospheric and structural conditions exist [1, 2]. In practice, the effects of the expected corrosion losses are typically eliminated by corrosion allowances which are added to the thickness of the element calculated in static analyses. The corrosion allowance in international standards is typically derived from a single parameter - the classified corrosion aggressiveness of atmospheres. Most constructions designed from the weathering steel which were built in the Czech Republic have been inspected and assessed over the last years. It follows from the inspections that more parameters should be taken into account in order to determine more exactly the corrosion losses and subsequently corrosion allowances, the corrosion aggressiveness only being not enough for this. The new analytical method for calculating corrosion allowances is introduced in this paper. The experimental corrosion tests that are carried on the existing weathering steel bridge structures in the Czech Republic are described in this paper as well. The influence of the position and location of the surface in the structure on the resulting corrosion rates can be evaluated using this experimental testing. Typical surfaces of steel bridges are tested, e.g. webs of main girders, upper and lower surfaces of flanges, surfaces affected by leaking salt solutions. Results of the corrosions tests can be used for the specification of the corrosion prediction model.
