DAMAGE DETECTION OF RC SLABS USING NONLINEAR VIBRATION FEATURES
This work studies the signatures of non-linear vibration characteristics of damaged reinforced concrete structures using wavelet transform with reference to their possible use to detect damage in reinforced concrete structures. A two-span RC slab built in 2003 was tested to failure in the laboratory. Vibration measurements were carried out at various stages of structural damage. The dynamic responses were analyzed in time-frequency domain by wavelet transform and the skeleton curve was constructed to describe the nonlinear characteristics in the reinforced concrete structures. The results show that the skeleton curves were good indicators of damage in the reinforced concrete structures.
