Abstract

Modal parameters are applied for prediction and analysis of structural behaviour and finite element model updating which is essential for a structural health monitoring system. This research proposes a revised procedure of modal parameter selection in frequency domain decomposition for operational modal analysis. The suggested method extracts modal parameters successfully and automatically.
