Identification of stiffness degradation in structures using wavelet analysis.Abstract An approach for structural health monitoring (SHM) and damage detection using a wavelet based time-frequency technique is not awayed here. The characteristics of dynamic answers of structures are studied through wavelet analysis. Inferences are drawn from the wavelet coefficients obtained. Numerical simulation data are used for the design of illustration. Two examples (i) a bi-linear constitution with breakable springs causing stiffness degradation and (ii) a hysteretic a whole with continuous variation in stiffness with nonlinearity involving displacement and velocity 00-00-0000 Index Corp., Stratford, Conn newly opened a new manufacturing/assembly operation.
