The contribution deals with some case studies of steel structure failures, which happened in Slovakia a few years ago. Features of cracking are illustrated on real cases of breakdowns in the transmission gas pipelines, at the cement works and in the petrochemical industry. All failures were caused by an incorrect technical approach. Possible remedial measures are proposed.
