Abstract

In this paper, several case studies will be presented in which calibration method of FEM models via structural natural frequencies identified onsite were applied. We can expect reliable analysis results from the well-calibrated model. Calibration is required to make the model, which includes, at least indirectly, any imperfection that exists in the structure, and which cannot be registered in any other way. Possibilities of structural health monitoring will be shown also, by comparing the natural frequencies obtained by measurements at different times: before, during and after the structural rehabilitation. This method is not omnipotent, so, except for the advantages, we shall show limitations of method related to the type of structure, weather conditions and other. Our experience with low-rise structures with great stiffness will be compared with the published experience of other authors.
