Originální abstrakt
The paper is focused on one particular step of methodology for dynamic identification using artificial neural networks and stratified simulation of Monte Carlo type. An influence of local decrease of stiffness on modal properties (eigenfrequencies and modeshapes) is studied. The role of the magnitude of damage is examined. The aim is determination of suitable initial parameters for consequent inverse analysis. Two approaches for modal properties calculation are used - one of them is particularly suitable for nonlinear problems. Two structures are used for the study: A simple cantilever beam and real bridge Z24 tested in Switzerland.
