This contribution deals with experimental corrosion tests carried out on the weathering steel railway bridge in Prague. The basic specific property of the weathering steel is an ability to create in favourable environment a protective patina layer on its surface. Since 1968 weathering steel is used under the name “Atmofix” in the Czech Republic and can be used as a standard structural material without any corrosion protection. The weathering steel Atmofix is mostly used for bridge structures and lattice transmission towers. Some of these constructions built in the Czech Republic have been assessed and inspected in the last few years. Authors of this paper developed a new methodology of non-destructive experimental testing of corrosion processes. Testing specimens are installed on typical surfaces of steel bridges in such a way to simulate real conditions of the examined surface. This paper describes results of corrosion tests (thickness of corrosion products, corrosion losses and X-Ray analysis) after one-year exposure, correlation factor and dependence of location.

The paper introduces the experimental corrosion tests that are carried out on the existing weathering steel bridges in the Czech Republic. 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. The corrosion tests to study the relation between steel grade (weathering steels S355J2WP and S355J2W) and corrosion rates are introduced in this paper as well.

Weathering structural steel has been used for various outdoor load-carrying structures (even without anti-corrosion surface protection) in the world as well as in the Czech Republic for about 45 years [1, 2, 3]. Load-carrying structures are designed for service life of as many as 100 years and the weathering steel can be used as a standard structural material without any corrosion protection. The weathering steel is able to create a protective patina layer on the surface in favourable environment; it means suitable atmospheric and structural conditions. A lot of constructions built from the weathering steel in the Czech Republic have been assessed and inspected in last few years. This paper describes the new developed method for experimental measuring of real corrosion losses on typical surfaces of bridges.

AbstractStructural health monitoring (SHM) can provide information needed to make important decisions regarding the maintenance of bridge structures. However, the data collected from monitoring needs to be first translated into actionable, quantitative or qualitative based characteristics, that indicate the condition of a bridge. This paper presents a process of evaluation of such performance indicator in case of a steel railway bridge using the updated FE model and in-situ measurements of strains on selected stringers and floorbeams.

This paper deals with the symbolic-aesthetic dimension of industrial and technical structures as a possible category for classifying and evaluating such structures. This category should play an important role in assessing the value of industrial and technical structures so that they are thoroughly and properly assessed as a part of our cultural heritage. This paper was presented at the XIII International TICCIH Congress in Terni in 2006.
