Description
Summary:This paper aims to investigate a methodology to determine the elastic parameters of a wood-steel composite floor using the dynamic characteristics determined experimentally. Analytical and experimental dynamic analyses of the wooden floor are performed and the results are presented. Test results showed that the natural frequency values coming from the experiments differ considerably from those coming from the analytical studies due to the material characteristic values taken into consideration. An automatic comparison of vibration mode shapes obtained by finite element analysis and experimentally is made in order to calibrate de FEM model. By calibrating the FEM model using results from the vibration modal identification, an assessment of the structural system parameters can be obtained. The automatic model updating procedure highlighted the real elasticity modulus of the wood used, identified by testing wood specimens.
