Description	Příspěvek popisuje metody použitelné pro únavové výpočty svařovaných tenkostěnných dutých profilů. Ukázány jsou příklady průmyslového použití přístupu přes konstrukční napětí a lokálního přístupu. Diskutovány jsou únavové testy a numerické a experimentální analýzi napětí v blízkosti svarové oblasti. Posouzení spolehlivosti svarů pomocí metody Monte Carlo je provedeno v programu Ant Hill. (cs) An analysis and assessment of the resistance of welded joints against fatigue is the main topic of the presented paper. The objective is to develop an expert system as a set of computer programs. The paper describes the project structure based on a computer-aided analysis of the dynamic response of a construction and a localization of welded nodes. The first level of the assessment is a classification of a welded joint into a particular type category. Categories are defined by the used material and by the weld shape arrangement. Using selected flags the Smith?s diagrams and fatigue curves are assigned to a node. The next step of the assessment is based on determination of weld node stresses. The approaches of nominal and shape stresses in the weld, or another approach using local stresses can be applied here. Criteria based on equivalent stresses according to a strength hypothesis (uniaxial approach) as well as multiaxial fatigue criteria can be used for a more detailed weld joint analysis.An analysis An analysis and assessment of the resistance of welded joints against fatigue is the main topic of the presented paper.
