Study of existing and newly developed weathering steels in respekt to their usage for steel structures

Research project MPO CR FT-TA5/076 (programnme TANDEM)

The project aim is the analysis of the stage of the existing steel structures made from weathering steels exposed for long-term period in various environments and evaluation of the specific corrosion stress in areas which may affect service life of structures, microclimatical parameters of structures and defekt and failure causes. The forming of protective patina layer, initial corrosion rate and other characteristics of weathering steels will be analysed in significantly changed conditions of atmospheric environments in teh Czech republic and in Europe too. The output of project will create the base for actualisation of technical standards, elaboration of software and maps for prediction of service life of weathering steels for new built and for existing structures.
