The article is to show results of numerical and experimental examination of changes in wave propagation in a composite rod with additional mass. For numerical modelling the spectral element method is used. For experimental verification the IFFM PAS laboratory equipment was used. As actuators and sensors PZT elements were utilised. The results obtained via numerical and experimental simulations are compared and discussed.

Abstract This paper presents the numerical modelling of strengthening a steel-concrete composite beam. The main assumption is that the strengthening is not the effect of the state of a failure of a structure, but it resulted from the need to increase the load-bearing capacity and stiffness of the structure (for example: due to a change in the use of the object). The expected solution is strengthening without the necessity to completely unload the structures (to reduce the scope of works, the cost of modernization and to shorten the time). The problem is presented on the example of a composite beam which was strengthened through welding a steel plate to the lower flange of the steel beam. The paper describes how energy parameters are used to evaluate the efficiency of structures’ strengthening and proposes an appropriate solution.

The paper presents the analysis of innovative precast hybrid structural elements. The elements are two-layered prefabricated lintels, which are made of AAC (aerated autoclaved concrete) and reinforced concrete, consisting of several hybrid modules used for closing any openings with spans varying between 0.75 m and 3.25 m. The presented study contains the analytical calculus, covered by numerical modelling simulations, which helped determining the modules’ load bearing capacity and support the authors’ conclusion to use these hybrid lintels as structural elements.
