Abstract:In the last two decades,the damage detection for civil engineering structures has been widely treated as a modal analysis problem and most of the currently available vibration-based system identification approaches are based on modal parameters,namely the natural frequencies,mode shapes and damping ratios,and/or their derivations,which are suitable for linear systems. Nonlinearity is generic in engineering structures. For example,the initiation and development of cracks in civil engineering stru...
