The paper presents analysis results of steel-concrete composite beams, identification and attempts to detect damage introduced in a discrete model. Analysis of damage detection was conducted using DDL (Damage, Detection, Localization), our own original algorithm. Changes of dynamic and static parameters of the model were analysed in damage detection. Discrete wavelet transform was used for damage...
Steel-concrete composite elements are very often used as main elements of floors or in bridge engineering as main carrying girders. This paper presents computational models and an analysis of natural vibrations conducted on steel-concrete composite beams. Simulation results were compared with experimental research results for beams in groups B1 and B2. In the group of beams B1 a connection that consisted...
Most technological machines generate vibrations which are transferred to either support systems or foundations. To ensure an object's safe operation, it is necessary to have adequate knowledge about dynamic properties of both machines and a supporting construction. A steel-concrete composite floor is an example of a supporting construction. It consists of steel beams connected with a reinforced concrete...
