Problems of steel construction modal models identification Problemy identyfikacji modeli modalnych stalowych ustrojów nośnych

Complex identification of steel construction modal models requires simultaneous numerical and experimental analysis of the object. Such an approach allows to obtain more accurate results while the methods complement each other. Results presented, concern stacker feeding bridge which operates in open pit mine. Operational modal analysis was made. Application of this method enables to assess influence of working condition on the modal characteristic. Experimental results were validated with use of numerical method.
