The subject of the topic is the analysis of the influence of damage of steel structures on their static and dynamic behaviour. The subject is to perform parametric studies with defined damage and degradation, focusing on historical riveted structures. The damage consists of both corrosion degradation and fatigue damage. The objective is to detect failure based on changes in mechanical, static or dynamic properties. In the case of dynamic properties, experimental analysis performed in a dense array of sensors, currently being developed in the Tacr project, will be used. Another objective is to identify external influences affecting the measured data, such as the influence of climatic conditions, and also to use artificial intelligence methods to eliminate them and predict the future behaviour.
